LTC7801 Datasheet (Analog Devices) - Synchronous Step-Down DC/DC Controller

LTC7801, Synchronous Step-Down DC/DC Controller

The LTC®7801 is a high performance step-down switching regulator DC/DC controller that drives an all N-channel synchronous power MOSFET stage that can operate from input voltages up to 140V.

A constant frequency current mode architecture allows a phase-lockable frequency of up to 850kHz.
