LTC3874-1 Datasheet (Analog Devices) - PolyPhase Step-Down Synchronous Slave Controller

LTC3874-1, PolyPhase Step-Down Synchronous Slave Controller

The LTC®3874-1 is a dual PolyPhase® current mode synchronous step-down slave controller.

It enables high current, multiphase applications when paired with a companion master controller by extending the phase count.

Compatible master controllers include the LTC3884-1, LTC3774, LTC3875, LTC3877 and LT
