LT3685 - 2.4MHz Step-Down Switching Regulator

📥 Download Datasheet

General Description

The LT®3685 is an adjustable frequency (200kHz to 2.4MHz) monolithic step-down switching regulator that accepts input voltages up to 38V operating and 60V maximum.

An internal overvoltage protection circuit turns off the power switch when VIN is above 38V typical (36V minimum) which then allows the part to safely withstand 60V transients.

A high efficiency 0.25 switch is included on the die along with a boost Schottky diode and the necessary oscillator, control, and logic circuitry.

Overview

LT3685 36V, 2A, 2.4MHz Step-Down Switching Regulator.
