Description

General part information

LTC3835 Series

The LTC3835 is a high performance step-down switching regulator controller that drives an all N-channel synchronous power MOSFET stage. A constant-frequency current mode architecture allows a phase-lockable frequency of up to 650kHz.The 80μA no-load quiescent current extends operating life in battery powered systems. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC3835 features a precision 0.8V reference and a power good output indicator. The 4V to 36V input supply range encompasses a wide range of battery chemistries.The TRACK/SS pin ramps the output voltage during startup. Current foldback limits MOSFET heat dissipation during short-circuit conditions.Comparison of LTC3835 and LTC3835-1PART #CLKOUT/PHASMDEXTVCCPGOODPACKAGESLTC3835YesYesYesFE20/4 × 5 QFNLTC3835-1NoNoNoGN16/3 × 5 DFNApplicationsAutomotive SystemsTelecom SystemsBattery-Operated Digital DevicesDistributed DC Power SystemsAll registered trademarks and trademarks are the property of their respective owners.
