With MODE pin set to low, at light load currents the converter can automaticallyenterPowerSaveModeandoperatestheninPFMmode. 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 through the high-side MOSFET switch through the inductortotheoutputcapacitorandload.Duringthisphase,thecurrentrampsupuntilthePWMcomparatortrips 12 SubmitDocumentationFeedback Copyright©2010–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS657051 TPS657052

The current limit comparator will also turn off the switch in case the current limit of the high-side MOSFET switch is exceeded. After an off 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. The next cycle will be initiated by the clock signal again turning off the low-side MOSFET rectifier and turning on the on the high-side MOSFET switch. The DCDC1 converter output voltage is set to 3.3 V and the DCDC2 converter output voltage is set to 1.8 V per default. A 180° phase shift between DCDC1 and DCDC2 decreases the input RMS current and synchronizes the operation of the two DC-DC converts. The FB pin must be directly connectedtotheoutputvoltageofDC-DCandnoexternalresistornetworkmustbeconnected. 8.3.2 PowerSaveMode ThePowerSaveModeisenabledwithModePinsettolow.Iftheloadcurrentdecreases,theconverterwillenter Power Save Mode operation automatically. During Power Save Mode the converter skips switching and operates with reduced frequency in PFM mode with a minimum quiescent current to maintain high efficiency. The converterwillpositiontheoutputvoltagetypically+1%abovethenominaloutputvoltage.Thisvoltagepositioning feature minimizes voltage drops caused by a sudden load step. The transition from PWM mode to PFM mode occurs once the inductor current in the low-side MOSFET switch becomes zero, which indicates discontinuous conduction mode. 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 VOUT nominal +1%, the device starts a PFM current pulse. The high-side MOSFET switch will turn on, and the inductor current ramps up. After the ON-time expires, the switch is turned off and the low-side MOSFET switch is turned on until the inductor current becomes zero. 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, thedevicestopsswitchingandentersasleepmodewithtypical25-µAcurrentconsumption. 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 voltage drops below the PFM comparator threshold. 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 is entered in case the output current can not longer be supported in PFM mode. The Power Save Mode can be disabledbysettingModepintohigh.Theconverterwillthenoperateinfixed-frequencyPWMmode. 8.3.2.1 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.

The output voltage ramps up from 5% to 95% of its nominal value within typical 250s. This limits the inrush current in the converter during ramp up and prevents possible input voltage drops when a battery or highimpedancepowersourceisused. EN 95% 5% VOUT t t Start RAMP Figure21.

Open core inductors have a soft saturation characteristic and they can usually handle higher inductor currents versusacomparableshieldedinductor. A more conservative approach is to select the inductor current rating just for the maximum switch current of the corresponding converter.
