LTC7803 Datasheet 3mhz Synchronous Step-down Controller

Manufacturer: Analog Devices

Overview: LTC7803 40V Low IQ, 3MHz Synchronous Step-Down Controller with Spread.

General Description

The LTC®7803 is a high performance, 100% Duty Cycle Capable, synchronous step-down DC/DC switching regulator controller that drives an all N-channel power MOSFET stage.

Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements.

A constant frequency current mode architecture allows a phase-lockable switching frequency of up to 3MHz.
