Description
General part information
LTC3835-1 Series
The LTC3835-1 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 LTC3835-1 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.CLKOUT/PHASMDEXTVCCPGOODPackageLTC3835YesYesYesTSSOP-20, 4x5 QFN-20LTC3835-1NoNoNoGN-16, 3x5 DFN-16ApplicationsAutomotive SystemsTelecom SystemsBattery-Operated Digital DevicesDistributed DC Power Systems
