Overview

The LT®8604/LT8604C is a compact, high speed synchronous monolithic step-down switching regulator that delivers up to 120mA to the output with high efficiency at a constant frequency, even up to 2.2MHz. It accepts a wide input voltage range up to 42V and consumes only 2.5µA of quiescent current when operating in Burst Mode.
