LTC3874 Datasheet Polyphase Step-down Synchronous Slave Controller

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3874 PolyPhase Step-Down Synchronous Slave Controller with Sub-Milliohm DCR.

General Description

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

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

Compatible master controllers include the LTC3884, LTC3866, LTC3875, LTC3877 and LTC3774.
