LTC3727A-1 - 2-Phase Synchronous Step-Down Switching Regulators

Description

The LTC®3727A-1 is a high performance dual step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages.

A constant frequency current mode architecture allows phase-lockable frequency of up to 550kHz.
