It provides up to 600-mA output current from a single Li-Ion cell and is ideal to power mobilephonesandotherportableapplications. With an wide input voltage range of 2 V to 6 V, the device supports applications powered by Li-Ion batteries with extendedvoltagerange,twoandthreecellalkalinebatteries,3.3-Vand5-Vinputvoltagerails. The TPS6226x operates at 2.25-MHz fixed switching frequency and enters Power Save Mode operation at light loadcurrentstomaintainhighefficiencyovertheentireloadcurrentrange. The Power Save Mode is optimized for low output voltage ripple. For low noise applications, the device can be forced into fixed frequency PWM mode by pulling the MODE pin high. In the shutdown mode, the current consumption is reduced to less than 1 μA. TPS6226x allows the use of small inductors and capacitors to achieve asmallsolutionsize.

At light load currents the converter can automatically enter Power SaveModeandoperatestheninPFMmode. During PWM operation the converter use a unique fast response voltage mode control scheme with input voltage feed-forward to achieve good line and load regulation allowing the use of small ceramic input and output capacitors. At the beginning of each clock cycle initiated by the clock signal, the High Side MOSFET switch is turned on. The current flows now from the input capacitor via the High Side MOSFET switch through the inductor to the output capacitor and load. During this phase, the current ramps up until the PWM comparator trips and the control logic will turn off the switch. The current limit comparator will also turn off the switch in case the current limit of the High Side MOSFET switch is exceeded. After a dead time preventing shoot through current, the Low Side MOSFET rectifier is turned on and the inductor current will ramp down. The current flows now from the inductor to the output capacitor and to the load. It returns back to the inductor through the Low Side MOSFET rectifier. ThenextcyclewillbeinitiatedbytheclocksignalagainturningofftheLowSideMOSFETrectifierandturningon theontheHighSideMOSFETswitch. POWER SAVE MODE The Power Save Mode is enabled with MODE Pin set to low level. If the load current decreases, the converter will enter Power Save Mode operation automatically. During Power Save Mode the converter skips switching and operateswithreducedfrequencyinPFMmodewithaminimumquiescentcurrenttomaintainhighefficiency.The converterwillpositiontheoutputvoltagetypically+1%abovethenominaloutputvoltage.Thisvoltagepositioning featureminimizesvoltagedropscausedbyasuddenloadstep. The transition from PWM mode to PFM mode occurs once the inductor current in the Low Side MOSFET switch becomeszero,whichindicatesdiscontinuousconductionmode. During the Power Save Mode the output voltage is monitored with a PFM comparator. As the output voltage falls below the PFM comparator threshold of V nominal +1%, the device starts a PFM current pulse. The High OUT Side MOSFET switch will turn on, and the inductor current ramps up. After the On-time expires, the switch is turnedoffandtheLowSideMOSFETswitchisturnedonuntiltheinductorcurrentbecomeszero. The converter effectively delivers a current to the output capacitor and the load. If the load is below the delivered current, the output voltage will rise. If the output voltage is equal or higher than the PFM comparator threshold, thedevicestopsswitchingandentersasleepmodewithtypical15μAcurrentconsumption. If the output voltage is still below the PFM comparator threshold, a sequence of further PFM current pulses are generated until the PFM comparator threshold is reached. The converter starts switching again once the output voltagedropsbelowthePFMcomparatorthreshold. With a fast single threshold comparator, the output voltage ripple during PFM mode operation can be kept small. The PFM Pulse is time controlled, which allows to modify the charge transferred to the output capacitor by the value of the inductor. The resulting PFM output voltage ripple and PFM frequency depend in first order on the size of the output capacitor and the inductor value. Increasing output capacitor values and inductor values will minimize the output ripple. The PFM frequency decreases with smaller inductor values and increases with larger values. The PFM mode is left and PWM mode entered in case the output current can not longer be supported in PFM mode.ThePowerSaveModecanbedisabledthroughtheMODEpinsettohigh.Theconverterwillthenoperate infixedfrequencyPWMmode. DynamicVoltagePositioning This feature reduces the voltage under/overshoots at load steps from light to heavy load and vice versa. It is active in Power Save Mode and regulates the output voltage 1% higher than the nominal value. This provides moreheadroomforboththevoltagedropataloadstep,andthevoltageincreaseataloadthrow-off.

PowerSaveModeOperationwithautomaticModetransition 100%DutyCycleLowDropoutOperation The device starts to enter 100% duty cycle mode once the input voltage comes close to the nominal output voltage. In order to maintain the output voltage, the High Side MOSFET switch is turned on 100% for one or morecycles. With further decreasing VIN the High Side MOSFET switch is turned on completely. In this case the converter offers a low input-to-output voltage difference. This is particularly useful in battery-powered applications to achievelongestoperationtimebytakingfulladvantageofthewholebatteryvoltagerange.

SOFT START The TPS6226x has an internal soft start circuit that controls the ramp up of the output voltage. The output voltage ramps up from 5% to 95% of its nominal value within typical 250μs. This limits the inrush current in the converter during ramp up and prevents possible input voltage drops when a battery or high impedance power sourceisused.Thesoftstartcircuitisenabledwithinthestartuptimet . StartUp SHORT-CIRCUIT PROTECTION The High Side and Low Side MOSFET switches are short-circuit protected with maximum switch current = I . LIMF The current in the switches is monitored by current limit comparators. Once the current in the High Side MOSFET switch exceeds the threshold of it's current limit comparator, it turns off and the Low Side MOSFET switch is activated to ramp down the current in the inductor and High Side MOSFET switch. The High Side MOSFET switch can only turn on again, once the current in the Low Side MOSFET switch has decreased below thethresholdofitscurrentlimitcomparator.

For stable operation, the L and C values of the output filter may not fall below 1μH effective inductanceand3.5μFeffectivecapacitance. InductorSelection The inductor value has a direct effect on the ripple current. The selected inductor has to be rated for its dc resistance and saturation current. The inductor ripple current (ΔI ) decreases with higher inductance and L increaseswithhigherV orV . I O TheinductorselectionhasalsoimpactontheoutputvoltagerippleinPFMmode.Higherinductorvalueswilllead to lower output voltage ripple and higher PFM frequency, lower inductor values will lead to a higher output voltageripplebutlowerPFMfrequency. Equation 1 calculates the maximum inductor current in PWM mode under static load conditions. The saturation current of the inductor should be rated higher than the maximum inductor current as calculated with Equation 2. This is recommended because during heavy load transient the inductor current will rise above the calculated value.

InputCapacitorSelection An input capacitor is required for best input voltage filtering, and minimizing the interference with other circuits caused by high input voltage spikes. For most applications, a 4.7μF to 10μF ceramic capacitor is recommended. Because ceramic capacitor loses up to 80% of its initial capacitance at 5 V, it is recommended that 10μF input capacitors be used for input voltages > 4.5V. The input capacitor can be increased without any limit for better input voltage filtering. Take care when using only small ceramic input capacitors. When a ceramic capacitor is used at the input and the power is being supplied through long wires, such as from a wall adapter, a load step at the output or VIN step on the input can induce ringing at the VIN pin.

Proper function of the device demands careful attention to PCB layout. Care must be taken in board layout to get the specified performance. If the layout is not carefully done, the regulator could show poor line and/or load regulation, stability issues as well as EMI problems. It is critical to provide a low inductance, impedance ground path. Therefore, use wide and short traces for the main current paths. The input capacitor should be placed as close as possible to the IC pins aswellastheinductorandoutputcapacitor. Connect the GND Pin of the device to the PowerPAD™ land of the PCB and use this pad as a star point. Use a common Power GND node and a different node for the Signal GND to minimize the effects of ground noise. Connect these ground nodes together to the PowerPAD land (star point) underneath the IC. Keep the common path to the GND PIN, which returns the small signal components and the high current of the output capacitors as shortaspossibletoavoidgroundnoise.TheFBlineshouldbeconnectedrighttotheoutputcapacitorandrouted awayfromnoisycomponentsandtraces(e.g.,SWline).
