TPS61070,TPS61071,TPS61072,TPS61073 www.ti.com SLVS510E–JULY2006–REVISEDMARCH2015 10 Detailed Description 10.1 Overview The TPS6107x devices provide a power supply solution for products powered by either a one-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery. Output currents can go as high as 75 mA while using a single-cell alkaline, and discharge it down to 0.9 V. It can also be used for generating 5 V at 200 mA from a 3.3 V rail or a Li-ion battery. The boost converter is based on a fixed frequency, pulse-width- modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. At low load currents the TPS61070 and TPS61073 enter the power-save mode to maintain a high efficiency over a wide load current range. The power-save mode is disabled in the TPS61071 and TPS61072, forcing the converters to operate at a fixed switching frequency. The maximum peak current in the boost switch is typically limited to a value of 600 mA. The TPS6107x output voltage is programmed by an external resistor divider. The converter can be disabled tominimizebatterydrain.Duringshutdown,theloadiscompletelydisconnectedfromthebattery. 10.2 Functional Block Diagram SW Backgate Control VBAT VOUT VOUT 5 kW 3 pF Vmax Gate Control Control GND Error Amplifier 160 kW 50 kW _ FB Regulator + 5 pF + Vref = 0.5 V _ GND Control Logic Oscillator Temperature Control EN GND 10.3 Feature Description 10.3.1 ControllerCircuit The controller circuit of the device is based on a fixed frequency multiple feedforward controller topology. Input voltage, output voltage, and voltage drop on the NMOS switch are monitored and forwarded to the regulator. So, changes in the operating conditions of the converter directly affect the duty cycle and must not take the indirect andslowwaythroughthecontrolloopandtheerroramplifier.Thecontrolloop,determinedbytheerroramplifier, only has to handle small signal errors. The input for it is the feedback voltage on the FB pin. It is compared with theinternalreferencevoltagetogenerateanaccurateandstableoutputvoltage.

The typical peak-current limit is set to 600 mA. An internal temperature sensor prevents the device fromgettingoverheatedincaseofexcessivepowerdissipation. 10.3.1.1 SynchronousRectifier The device integrates an N-channel and a P-channel MOSFET transistor to realize a synchronous rectifier. Because the commonly used discrete Schottky rectifier is replaced with a low R PMOS switch, the power DS(on) conversionefficiencyreachesvaluesabove90%.Aspecialcircuitisappliedtodisconnecttheloadfromtheinput during shutdown of the converter. In conventional synchronous rectifier circuits, the backgate diode of the high- side PMOS is forward biased in shutdown and allows current flowing from the battery to the output. However, this device uses a special circuit which takes the cathode of the backgate diode of the high-side PMOS and disconnectsitfromthesourcewhentheregulatorisnotenabled(EN=low). The benefit of this feature for the system design engineer is that the battery is not depleted during shutdown of the converter. No additional components must be added to the design to make sure that the battery is disconnectedfromtheoutputoftheconverter. 10.3.1.2 DeviceEnable The device is put into operation when EN is set high. It is put into a shutdown mode when EN is set to GND. In shutdown mode, the regulator stops switching, all internal control circuitry is switched off, and the load is isolated from the input (as described in the Synchronous Rectifier section). This also means that the output voltage can drop below the input voltage during shutdown. During start-up of the converter, the duty cycle and the peak currentarelimitedinordertoavoidhigh-peakcurrentsdrawnfromthebattery. 10.3.1.3 UndervoltageLockout An undervoltage lockout function prevents the device from operating if the supply voltage on VBAT is lower than approximately 0.8 V. When in operation and the battery is being discharged, the device automatically enters the shutdown mode if the voltage on VBAT drops below approximately 0.8 V. This undervoltage lockout function is implementedinordertopreventthemalfunctioningoftheconverter. 10.3.1.4 SoftStartandShort-CircuitProtection When the device enables, the internal start-up cycle starts with the first step, the precharge phase. During precharge, the rectifying switch is turned on until the output capacitor is charged to a value close to the input voltage. The rectifying switch is current limited during this phase. The current limit increases with the output voltage. This circuit also limits the output current under short-circuit conditions at the output.

PrechargeandShort-CircuitCurrent After charging the output capacitor to the input voltage, the device starts switching. If the input voltage is below 1.8 V, the device works with a fixed duty cycle of 70% until the output voltage reaches 1.8 V. After that the duty cycle is set depending on the input output voltage ratio. Until the output voltage reaches its nominal value, the boostswitchcurrentlimitissetto50%ofitsnominalvaluetoavoidhighpeakcurrentsatthebatteryduringstart- up. As soon as the output voltage is reached, the regulator takes control, and the switch current limit is set back to100%. 10.4 Device Functional Modes 10.4.1 Power-SaveMode The TPS61070 and TPS61073 are capable of operating in two different modes. At light loads, when the inductor current becomes zero, they automatically enter the power-save mode to improve efficiency. In the power-save mode, the converters only operate when the output voltage trips below a set threshold voltage. It ramps up the output voltage with one or several pulses and returns to the power-save mode once the output voltage exceeds the set threshold voltage. If output power demand increases and the inductor current no longer goes below zero, the device again enters the fixed PWM mode. In this mode, there is no difference between the PWM only versionsTPS61071andTPS61072andthepower-savemodeenabledversionsTPS61070andTPS61073.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 11.1 Application Information The TPS6107x DC-DC converters are intended for systems powered by a single-cell, up to triple-cell alkaline, NiCd, NiMH battery with a typical terminal voltage between 0.9 V and 5.5 V. They can also be used in systems powered by one-cell Li-Ion or Li-Polymer with a typical voltage between 2.5 V and 4.2 V. Additionally, any other voltage source with a typical output voltage between 0.9 V and 5.5 V can power systems where the TPS6107x is used. Due to the nature of boost converters, the output voltage regulation is only maintained when the input voltageappliedislowerthantheprogrammedoutputvoltage. 11.2 Typical Application L1 SW VOUT VCC C2 Boost Output R1 VBAT FB Power C1 R2 EN Supply GND TPS61070 Figure12. TypicalApplicationCircuitforAdjustableOutputVoltageOption 11.2.1 DesignRequirements In this example, TPS61070 is used to design a 3.3-V power supply with 75-mA output current capability. The TPS61200canbepoweredbyeitherasingle-cell,two-cell,orthree-cellalkaline,NiCdorNiMH,orone-cellLi-Ion or Li-Polymer battery. In this example, the input voltage range is from 0.9 V to 1.65 V for single-cell alkaline input design. 11.2.2 DetailedDesignProcedure 11.2.2.1 ProgrammingtheOutputVoltage TheoutputvoltageoftheTPS6107xdc/dcconvertercanbeadjustedwithanexternalresistordivider.Thetypical value of the voltage at the FB pin is 500 mV. The maximum recommended value for the output voltage is 5.5 V. The current through the resistive divider should be about 100 times greater than the current into the FB pin. The typical current into the FB pin is 0.01 µA, and the voltage across R2 is typically 500 mV. Based on those two values,therecommendedvalueforR2shouldbelowerthan500kΩ,inordertosetthedividercurrentat1 µAor higher. Because of internal compensation circuitry, the value for this resistor should be in the range of 200 kΩ. Fromthat,thevalueofresistorR1,dependingontheneededoutputvoltage(V ),iscalculatedusingEquation1: O (cid:4)V (cid:5) (cid:4) V (cid:5) R1(cid:3)R2(cid:1) O (cid:2)1 (cid:3)180k(cid:1)(cid:1) O (cid:2)1 V 500mV FB (1) For example, if an output voltage of 3.3 V is needed, a 1 MΩ resistor should be chosen for R1. If for any reason the value chosen for R2 is significantly lower than 200 kΩ, additional capacitance in parallel to R1 is recommended, if the device shows instable regulation of the output voltage.

A boost inductor and a storage capacitor at the output are required. To select the boost inductor, it is recommended to keep the possible peak inductor current below the current limit threshold of the power switch in the chosen configuration. For example, the current limit threshold of the TPS6107x's switch is 600 mA. The highest peak current through the inductor and the switch depends on the output load, the input (V ), and the BAT outputvoltage(V ).EstimationofthemaximumaverageinductorcurrentisdoneusingEquation3: OUT VOUT =I ´ L O VBAT´0.8 (3) For example, for an output current of 75 mA at 3.3 V, at least 340 mA of average current flows through the inductorataminimuminputvoltageof0.9V. The second parameter for choosing the inductor is the desired current ripple in the inductor. Normally, it is advisable to work with a ripple of less than 20% of the average inductor current. A smaller ripple reduces the magnetic hysteresis losses in the inductor, as well as output voltage ripple and EMI. But in the same way, regulation time rises at load changes. In addition, a larger inductor increases the total system costs. With these parameters,itispossibletocalculatethevaluefortheinductorbyusingEquation4: VBAT´(VOUT-VBAT) L = DI ´f´VOUT L (4) Parameter f is the switching frequency and ΔI is the ripple current in the inductor, i.e., 40% ΔI . In this example, L L thedesiredinductorhasthevalueof4µH.Withthiscalculatedvalueandthecalculatedcurrents,itispossibleto choose a suitable inductor. In typical applications, a 4.7-µH inductance is recommended. The device has been optimized to operate with inductance values between 2.2 µH and 10 µH. Nevertheless, operation with higher inductance values may be possible in some applications. Detailed stability analysis is then recommended. Care must be taken because load transients and losses in the circuit can lead to higher currents as estimated in Equation 4. Also, the losses in the inductor caused by magnetic hysteresis losses and copper losses are a major parameterfortotalcircuitefficiency.

This ripple is determined by two parameters of the capacitor, the capacitance and the ESR. It is possible to calculate the minimum capacitance needed for the defined ripple, supposing that the ESR is zero, by usingEquation5: I ´(VOUT-VBAT) C = O min f´DV´VOUT (5) ParameterfistheswitchingfrequencyandΔVisthemaximumallowedripple. With a chosen ripple voltage of 10 mV, a minimum capacitance of 4.5 µF is needed. In this value range, ceramic capacitors are a good choice. The ESR and the additional ripple created are negligible. It is calculated using Equation6: DV =I ´R ESR O ESR (6) The total ripple is the sum of the ripple caused by the capacitance and the ripple caused by the ESR of the capacitor. Additional ripple is caused by load transients. This means that the output capacitor has to completely supply the load during the charging phase of the inductor. The value of the output capacitance depends on the speed of the load transients and the load current during the load change. With the calculated minimum value of 4.5 µFandloadtransientconsiderations,therecommendedoutputcapacitancevalueisina10 µFrange. Care must be taken on capacitance loss caused by derating due to the applied dc voltage and the frequency characteristic of the capacitor. For example, larger form factor capacitors (in 1206 size) have their self resonant frequencies in the same frequency range as the TPS6107x operating frequency. So the effective capacitance of the capacitors used may be significantly lower. Therefore, the recommendation is to use smaller capacitors in parallelinsteadofonelargercapacitor. 11.2.2.4 SmallSignalStability To analyze small signal stability in more detail, the small signal transfer function of the error amplifier and the regulator,whichisgiveninEquation7,canbeused: d 5´(R1+R2) A = = (REG) V R2´(1+i´w´0.8ms) (FB) (7) 11.2.3 ApplicationCurves FIGURE Outputvoltageincontinuousmode(TPS61071) Figure13 Outputvoltageincontinuousmode(TPS61071) Figure14 Outputvoltageinpower-savemode(TPS61070) Figure15 Outputvoltageinpower-savemode(TPS61070) Figure16 Loadtransientresponse(TPS61071) Figure17 Loadtransientresponse(TPS61071) Figure18 Linetransientresponse(TPS61071) Figure19 Linetransientresponse(TPS61071) Figure20 Start-upafterenable(TPS61070) Figure21 Start-upafterenable(TPS61070) Figure22 Start-upafterenable(TPS61071) Figure23 Start-upafterenable(TPS61071) Figure24 14 SubmitDocumentationFeedback Copyright©2006–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS61070 TPS61071 TPS61072 TPS61073

The input supply should be well regulated with the rating of TPS6107x. If the input supply is located more than a few inches from the device, additional bulk capacitance may be required in addition to the ceramic bypasscapacitors.Anelectrolyticortantalumcapacitorwithavalueof47 µFisatypicalchoice. 13 Layout 13.1 Layout Guidelines As for all switching power supplies, the layout is an important step in the design, especially at high-peak currents and high switching frequencies. If the layout is not carefully done, the regulator could show stability problems as well as EMI problems. Therefore, use wide and short traces for the main current path and for the power ground tracks. The input capacitor, output capacitor, and the inductor should be placed as close as possible to the IC. Use a common ground node for power ground and a different one for control ground to minimize the effects of groundnoise.ConnectthesegroundnodesatanyplaceclosetothegroundpinoftheIC. The feedback divider should be placed as close as possible to the ground pin of the IC. To lay out the control ground, it is recommended to use short traces as well, separated from the power ground traces. This avoids ground shift problems, which can occur due to superimposition of power ground current and control ground current. 13.2 Layout Example Top Bottom xxx R2 R1 VBAT xxxxxxxxxx C IN L xATxUT xxB xx B O F V V xxxx VOUT C xSWxGND xEN x OUT GND xx Figure30.
