LTC3807 - Synchronous Step-Down Controller

General Description

The LTC®3807 is a high performance step-down switching regulator DC/DC 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 750kHz.
