It runs at an oscillator frequency of 500 kHz. The current sense is implemented by measuring the voltage across the switch. The controller also limits the current through the power switch on a pulse-by-pulse basis. Care must be taken that the inductor saturation current is higher than the current limit of the TPS6100x. This prevents the inductor from going into saturation and therefore protects both device and inductor.Thecurrentlimitshouldnotbecomeactiveduringnormaloperatingconditions. The TPS6100x is designed for high efficiency over a wide output current range. Even at light loads the efficiency stayshighbecausethecontrollerentersapower-savemode,minimizingswitchinglossesoftheconverter.Inthis mode, the controller only switches if the output voltage trips below a set threshold voltage. It ramps up the output voltage with one or several pulses, and again goes into the power-save mode once the output voltage exceeds the threshold voltage. The controller enters the power-save mode when the output current drops to levels that force the discontinuous current mode. It calculates a minimum duty cycle based on input and output voltage and usesthecalculationforthetransitionoutofthepower-savemodeintocontinuouscurrentmode. The control loop must be externally compensated with an R/C/C network connected to the COMP pin. See the applicationsectionformoredetailsonthedesignofthecompensationnetwork. 9.3.2 DeviceEnable The device is put into operation when EN is set high. During start-up of the converter the input current from the battery is limited until the voltage on COMP reaches its operating point. The device is put into a shutdown mode when EN is set to GND. In this mode, the regulator stops switching and all internal control circuitry including the low-battery comparator is switched off. The output voltage drops to one diode drop below the input voltage in shutdown. 9.3.3 UndervoltageLockout An undervoltage lockout function prevents the device start-up if the supply voltage on V is lower than BAT approximately 0.7 V. This undervoltage lockout function is implemented in order to prevent the malfunctioning of the converter. When in operation and the battery is being discharged, the device automatically enters the shutdownmodeifthevoltageonV dropsbelowapproximately0.7V. BAT If the EN pin is hardwired to V and if the voltage at V drops temporarily below the UVLO threshold voltage, BAT BAT the device switches off and does not start up again automatically, even if the supply voltage rises above 0.9 V. The device starts up again only after a signal change from low to high on EN or if the battery voltage is completelyremoved. 9.3.4 Low-BatteryDetectorCircuit(LBIandLBO) The low-battery detector circuit is typically used to supervise the battery voltage and to generate an error flag when the battery voltage drops below a user-set threshold voltage. The function is active only when the device is enabled. When the device is disabled, the LBO pin is high impedance. The LBO pin goes active low when the voltage on the LBI pin decreases below the set threshold voltage of 500 mV ±15 mV, which is equal to the internalreferencevoltage.Thebatteryvoltage,atwhichthedetectioncircuitswitches,canbeprogrammedwitha resistive divider connected to the LBI pin. The resistive divider scales down the battery voltage to a voltage level of 500 mV, which is then compared to the LBI threshold voltage. The LBI pin has a built-in hysteresis of 10 mV. SeetheapplicationsectionformoredetailsabouttheprogrammingoftheLBIthreshold. If the low-battery detection circuit is not used, the LBI pin should be connected to GND (or to V ) and the LBO BAT pincanbeleftunconnected.DonotlettheLBIpinfloat. 9.3.5 Low-EMISwitch The device integrates a circuit which removes the ringing that typically appears on the SW-node when the converterentersthediscontinuouscurrentmode.Inthiscase,thecurrentthroughtheinductorrampstozeroand the Schottky diode stops conducting. Due to remaining energy that is stored in parasitic components of the diode, inductor, and switch, a ringing on the SW pin is induced.

This OUT voltage indicates when the diode is reverse biased. The ringing on the SW-node is damped to a large degree, reducingtheelectromagneticinterferencegeneratedbytheswitchingregulatortoagreatextent. 9.3.6 AdjustableOutputVoltage(TPS61000andTPS61007Only) The accuracy of the internal voltage reference, the controller topology, and the accuracy of the external resistor divider determine the accuracy of the adjustable output voltage versions. The reference voltage has an accuracy of ±4% over line, load, and temperature. The controller switches between fixed frequency and pulse-skip mode, depending on load current. This adds an offset to the output voltage that is equivalent to 1% of V . Using 1% O accurate resistors for the feedback divider, a total accuracy of ±6% can be achieved over the complete temperature and output current range. The TPS61007 is an improved adjustable output voltage version. Ground shift in the feedback loop was eliminated by adding a separate ground pin for the feedback resistor divider (FBGND). 9.4 Device Functional Modes 9.4.1 PowerSaveMode The TPS6100x enters a power-save mode, minimizing switching losses of the converter. In this mode, the controller only switches if the output voltage trips below a set threshold voltage. It ramps up the output voltage with one or several pulses, and again goes into the power-save mode once the output voltage exceeds the thresholdvoltage.

The typical value of the voltage on the FB pin is 500 mV in fixed-frequency operation and 485 mV in the power-save operation mode. The maximum allowed value for the output voltage is 3.3 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 R4 is typically 500 mV. Based on those two values, the recommended value for R4 is in the range of 500 kΩ in order to set the divider current at 1 µA.

The typical current into the LBI pin is 0.01 µA. The voltage across R2 is equal to the reference voltage that is generated on-chip, which has a value of 500 mV ±15 mV. The recommended value for R2 is therefore in the range of 500 kΩ.

The output of the low battery comparator is a simple open-drain output that goes active low if the battery voltage drops below the programmed threshold voltage on LBI. The output requires a pullup resistor with a recommended value of 1MΩ, and should only be pulled up to the V . If not used, the LBO pin can be left OUT floating. 10.2.2.3 InductorSelection The output filter of inductive switching regulators is a low pass filter of second order. It consists of an inductor andacapacitor,oftenreferredtoasstorageinductorandoutputcapacitor. To select an inductor, keep the possible peak inductor current below the current limit threshold of the power switch in your chosen configuration. For example, the current limit threshold of the TPS61006’s switch is 1100 mA at an output voltage of 3.3 V. The highest peak current through the inductor and the switch depends on the output load, the input (V ), and the output voltage (V ). Estimation of the maximum average inductor current BAT OUT canbedoneusingthefollowingequation: V I I u OUT L OUT V u0.8 BAT (3) For example, for an output current of 100 mA at 3.3 V, at least 515-mA current flows through the inductor at a minimuminputvoltageof0.8V. 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, the regulationtimeatloadchangerises.Inaddition,alargerinductorincreasesthetotalsystemcost.

(5) With a chosen ripple voltage of 15 mV, a minimum capacitance of 10 µF is needed. The total ripple will be larger due to the ESR of the output capacitor. This additional component of the ripple can be calculated using the followingequation: 'V I uR ESR OUT ESR (6) An additional ripple of 30 mV is the result of using a tantalum capacitor with a low ESR of 300 mΩ. The total ripple is the sum of the ripple caused by the capacitance and the ripple caused by the ESR of the capacitor. In this example, the total ripple is 45 mV. It is possible to improve the design by enlarging the capacitor or using smaller capacitors in parallel to reduce the ESR or by using better capacitors with lower ESR, like ceramics. For example, a 10-µF ceramic capacitor with an ESR of 50 mΩ is used on the evaluation module (EVM). Tradeoffs havetobemadebetweenperformanceandcostsoftheconvertercircuit. A 10-µF input capacitor is recommended to improve transient behavior of the regulator. A ceramic capacitor or a tantalumcapacitorwitha100-nFceramiccapacitorinparallelplacedclosetotheICisrecommended. 10.2.2.5 RectifierSelection The rectifier diode has a major impact on the overall converter efficiency.

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 ground noise. Connect these ground nodes at any place close to one of the ground pins of the IC. 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,whichcanoccurduetosuperimpositionofpowergroundcurrentandcontrolgroundcurrent. 12.2 Layout Example GND D N G VOUT LBO ILB C/FB W BAT N S V VIN 8 7 6 5 6 TPS6100x GND 1 2 3 4 3 EN FB ND UT GND P G O M V O C VOUT Figure24.
