TPS61200,TPS61201,TPS61202 www.ti.com SLVS577E–MARCH2007–REVISEDDECEMBER2014 10 Detailed Description 10.1 Overview The TPS6120x is a low input voltage synchronous boost converter family. The devices support 0.3-V to 5.5-V input voltage range, so can provide power supply solutions for products powered by either a single-cell, two-cell, orthree-cellalkaline,NiCdorNiMH,orone-cellLi-IonorLi-polymerbattery.Itisalsousedinfuelcellorsolarcell powered devices where the capability of handling low input voltages is essential. The devices provide output currents of up to 600 mA at a 5-V output, while using a single-cell Li-Ion or Li-Polymer battery and discharges it down to 2.6 V. The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters the Power Save mode to maintain a high efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to operate at a fixed switching frequency. The average input current is limited to a maximum value of 1500 mA. The output voltage is programmed by an external resistor divider, or is fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, the load is completelydisconnectedfromthebattery. 10.2 Functional Block Diagram L VOUT VAUX VCC Current Control VOUT Sensor PGND VIN Gate VCC Control Modulator FB V FB PS Oscillator EN Device Control UVLO Thermal PGND Shutdown GND PGND Copyright©2007–2014,TexasInstrumentsIncorporated SubmitDocumentationFeedback 11 ProductFolderLinks:TPS61200 TPS61201 TPS61202
TPS61200,TPS61201,TPS61202 SLVS577E–MARCH2007–REVISEDDECEMBER2014 www.ti.com 10.3 Feature Description 10.3.1 ControllerCircuit The controlling circuit of the device is based on an average current mode topology. The average inductor current is regulated by a fast current regulator loop which is controlled by a voltage control loop. The controller also uses input and output voltage feedforward. Changes of input and output voltage are monitored and immediately change the duty cycle in the modulator to achieve a fast response to those errors. The voltage error amplifier gets its feedback input from the FB pin. For adjustable output voltage devices, a resistive voltage divider must be connected to that pin. For fixed output voltage devices, FB must be connected to the output voltage to directly sense the voltage. Fixed output voltage versions use a trimmed internal resistive divider. The feedback voltage is comparedwiththeinternalreferencevoltagetogenerateastableandaccurateoutputvoltage. Thecontrollercircuitalsosensestheaverageinputcurrentaswellasthepeakinputcurrent.Thus,themaximum input power is controlled as well as the maximum peak current, to achieve a safe and stable operation under all possibleconditions.Toprotectthedevicefromoverheating,aninternaltemperaturesensorisimplemented. 10.3.1.1 SynchronousOperation The device uses three internal N-channel MOSFETs to maintain synchronous power conversion at all possible operating conditions. This enables the device to keep high efficiency over a wide input voltage and output power range. To avoid ground shift problems due to the high currents in the switches, two separate ground pins, GND and PGND, are used. The reference for all control functions is the GND pin. The power switches are connected to PGND. Both grounds must be connected on the PCB at only one point, ideally close to the GND pin. Due to the 3-switchtopology,theloadisalwaysdisconnectedfromtheinputduringshutdownoftheconverter. 10.3.1.2 DownRegulation A boost converter only regulates output voltages which are higher than the input voltage. This device operates differently. For example, it is able to regulate 3 V at the output with two fresh alkaline cells at the input having a total cell voltage of 3.2 V. Another example is powering white LEDs with a forward voltage of 3.6 V from a fully charged Li-Ion cell with an output voltage of 4.2 V. To control these applications properly, a Down Conversion modeisimplemented. If the input voltage reaches or exceeds the output voltage, the converter automatically changes to a Down Conversion mode. In this mode, the control circuit changes the behavior of the two rectifying switches. While continuing switching, it sets the voltage drop across the rectifying switches as high as needed to regulate the output voltage. This means the power losses in the converter increase. This must be taken into account for thermalconsideration. 10.3.1.3 DeviceEnable The device is put into operation when EN is set high. It is put into Shutdown mode when EN is set to low. In Shutdown mode, the regulator stops switching, all internal control circuitry including the UVLO comparator is switched off, and the load is disconnected from the input. Current does not flow from input to output or from outputtoinput.Thisalsomeansthattheoutputvoltagecandropbelowtheinputvoltageduringshutdown. 10.3.1.4 SoftstartandShort-CircuitProtection During start-up of the converter, the duty cycle and the peak current are limited in order to avoid high peak currentsdrawnfromthebattery.Afterbeingenabled,thedevicestartsoperating.Atfirst,itkeepsthemainoutput VOUTdisconnected,andchargesthecapacitoratVAUX.OncethecapacitoratVAUXischargedtoabout2.5V, the device switches to normal operation. This means VOUT is turned on and the capacitor at VOUT is charged, while the load connected to the device is supplied. To ramp up the output voltage in a controlled way, the average current limit is set to 400 mA and rises proportional to the increase of the output voltage. At an output voltage of about 1.2 V the current limit is at its nominal value. If the output voltage does not increase, the current limit does not increase. There is no timer implemented. Thus the output voltage overshoot at startup, as well as theinrushcurrent,iskeptataminimum.Thedevicerampsuptheoutputvoltageinacontrolledmannerevenifa large capacitor is connected at the output. When the output voltage does not increase above 1.2 V, the device assumes a short-circuit at the output, and keeps the current limit low to protect itself and the application.

In a boost connector, this is the input current. If an excessive load requires an input current greater than the average current limit, the device limits the input currentbyreducingtheoutputpowerdelivered.Inthiscase,theoutputvoltagedecreases. 10.3.1.6 UndervoltageLockout An undervoltage lockout function prevents the main output at VOUT from being supplied if the voltage at the UVLO pin drops below 0.25 V. When using a resistive divider at the voltage to be monitored, for example the supplyvoltage,anythresholdforthemonitoredvoltagecanbeprogrammed.Ifinundervoltagelockoutmode,the device still maintains its supply voltage at VAUX, and it is not turned off until EN is programmed low. This undervoltagelockoutfunctionisimplementedinordertopreventthemalfunctioningoftheconverter. 10.3.1.7 ThermalShutdown The device has a built-in temperature sensor which monitors the internal IC temperature. If the temperature exceeds the programmed threshold (see electrical characteristics table), the device stops operating. As soon as the IC temperature has decreased below the programmed threshold, it starts operating again. There is a built-in hysteresistoavoidunstableoperationatICtemperaturesatthethermalshutdownthreshold. 10.4 Device Functional Modes 10.4.1 PowerSaveMode The Power Save (PS) pin can be used to select different operation modes. To enable Power Save mode the PS pin must be set low. Power Save mode is used to improve efficiency at light load. If Power Save mode is enabled, the converter stops operating if the average inductor current decreases below about 300 mA and the output voltage is at or above its nominal value. If the output voltage decreases below its nominal value, the device ramps up the output voltage again by starting operation using a programmed average inductor current higher than required by the current load condition. Operation can last for one or several pulses. The converter stopsoperatingoncetheconditionsforstoppingoperationaremetagain. The Power Save mode can be disabled by programming a high at the PS pin. In Down Conversion mode, Power Save mode is always enabled and the device cannot be forced into fixed frequency operation at light loads. The PSinputsupportsstandardlogicthresholds. 10.4.2 DownConversionMode If the input voltage reaches or exceeds the output voltage, the converter automatically changes to a Down Conversion mode. In this mode, the control circuit changes the behavior of the two rectifying switches. While continuing switching, it sets the voltage drop across the rectifying switches as high as needed to regulate the output voltage. This means the power losses in the converter increase. This must be taken into account for thermalconsideration. Copyright©2007–2014,TexasInstrumentsIncorporated SubmitDocumentationFeedback 13 ProductFolderLinks:TPS61200 TPS61201 TPS61202

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 11.1 Application Information The TPS6120x DC-DC converters are intended for systems powered by a single up to triple cell Alkaline, NiCd, NiMH battery with a typical terminal voltage between 0.7 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.

To properly configure the fixed output voltage devices, the FB pin is used to sense the output voltage. This means that it must be connected directly to VOUT. For the adjustable output voltage version, an external resistor divider is used to adjust the output voltage. The resistor divider must be connected between VOUT, FB and GND. When the output voltage is regulated properly, the typical value of the voltage at the FB pin is 500 mV.

Based on those two values, the recommendedvalueforR2shouldbelowerthan500kΩ,inordertosetthedividercurrentat1 μAorhigher.Itis recommended to keep the value for this resistor in the range of 200 kΩ. The value of the resistor connected between VOUT and FB, R1, depending on the needed output voltage (V ), can be calculated using OUT Equation1: æV ö OUT R1=R2x ç -1÷ V è FB ø (1) As an example, for an output voltage of 3.3 V, a 1-MΩ resistor should be chosen for R when a 180-kΩ is 1 selectedforR . 2 11.2.2.2 ProgrammingtheUVLOThresholdVoltage The UVLO input can be used to shut down the main output if the supply voltage is getting too low. The internal reference threshold is typically 250 mV. If the supply voltage should cause the shutdown when it is dropping below250mV,V canbeconnecteddirectlytotheUVLOpin.Iftheshutdownshouldhappenathighervoltages, IN a resistor divider can be used. R3 and R4 in Figure 15 show an example of how to monitor the input voltage of the circuit. The current through the resistive divider should be about 100 times greater than the current into the UVLO pin. The typical current into the UVLO pin is 0.01 μA, and the voltage across R4 is equal to the UVLO voltagethresholdthatisgeneratedon-chip,whichhasavalueof250mV.Therefore,therecommendedvaluefor R4 is in the range of 250 kΩ. From this, the value of resistor R3, depending on the desired shutdown voltage V canbecalculatedusingEquation2.

V is the maximum input MIN IN voltage. The recommended inductor value range is between 1.5 μH and 4.7 μH. The minimum inductor value should not be below 1.5 μH, even if Equation 3 yields something lower. Using 2.2 μH is recommended anyway forgettingbestperformanceoverthewholeinputandoutputvoltagerange. With the chosen inductance value, the peak current for the inductor in steady state operation can be calculated usingEquation4. VOUT x IOUT VIN x (VOUT -VIN) I = + LMAX 0.8 xV 2 xV xfxL IN OUT (4) This would be the critical value for the current rating for selecting the inductor. It also needs to be taken into account that load transients and error conditions may cause higher inductor currents.

This is required to maintain control loop stability. There are no additional requirements regarding minimum ESR. There is also no upper limit for the output capacitance value.

At output voltages below 2.5 V, the capacitance should be in the range of 1 μF. Since this capacitor is also used as a snubber capacitor for the main switch, using a X5R or X7R ceramic capacitor with lowESRisimportant. 11.2.3 ApplicationCurves FIGURE OutputVoltageTPS61201,PowerSaveModeDisabled Figure16 OutputVoltageTPS61202,PowerSaveModeDisabled Figure17 OutputVoltageTPS61201,PowerSaveModeEnabled Figure18 OutputVoltageTPS61202,PowerSaveModeEnabled Figure19 TPS61201LoadTransientResponse Figure20 TPS61202LoadTransientResponse Figure21 TPS61201LineTransientResponse Figure22 TPS61202LineTransientResponse Figure23 TPS61201StartupafterEnable Figure24 TPS61202StartupafterEnable Figure25 16 SubmitDocumentationFeedback Copyright©2007–2014,TexasInstrumentsIncorporated ProductFolderLinks:TPS61200 TPS61201 TPS61202

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 and output capacitor, as well as 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.ConnectthesegroundnodesatanyplaceclosetooneofthegroundpinsoftheIC. The feedback divider should be placed as close as possible to the control 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 groundcurrent.SeeFigure29fortherecommendedlayout. 13.2 Layout Example Figure29. EVMLayout 13.3 Thermal Considerations Implementation of integrated circuits in low-profile and fine-pitch surface-mount packages typically requires special attention to power dissipation.
