LT8604 Datasheet High Efficiency 42v/120ma Synchronous Buck

Manufacturer: Analog Devices

Overview: LT8604/LT8604C High Efficiency 42V/120mA Synchronous Bucks.

General Description

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.

Top and bottom power switches are included with all necessary circuitry to minimize the need for external components.
