LTC3855 Datasheet (Linear Technology) - Multiphase Synchronous DC/DC Controller

LTC3855, Multiphase Synchronous DC/DC Controller

The LTC®3855 is a dual PolyPhase® current mode synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages.

It includes a high speed differential remote sense amplifier.

The maximum current sense voltage is programmable for either 30mV, 50mV or 75mV, allowing t
