LTC7810 Datasheet (Analog Devices) - 2-Phase Synchronous Step-Down DC/DC Controller

LTC7810, 2-Phase Synchronous Step-Down DC/DC Controller

The LTC®7810 is a high performance dual step-down DC/ DC switching regulator controller that drives all N-channel synchronous power MOSFET stages that can operate from voltages up to 140V.

A constant frequency current mode architecture allows a phase-lockable frequency of up to 720kHz.
