XL2576

3A 52KHz 40V Buck DC to DC Converter

Features

General Description

Wide 4.5V to 40V Input Voltage Range

5V,12V and adjustable versions

Output Adjustable from 1.23V to 37V

The XL2576 is a 52 KHz fixed frequency

PWM buck (step-down) DC/DC converter,

capable of driving a 3A load with high

efficiency, low ripple and excellent line and

load regulation. Requiring a minimum

number of external components, the regulator

is simple to use and include internal

Maximum Duty Cycle 100%

Minimum Drop Out 1.5V

fixed-frequency oscillator.

The PWM control circuit is able to adjust the

duty ratio linearly from 0 to 100%. An enable

function, an over current protection function

is built inside. An internal compensation

block is built in to minimize external

component count.

ON/OFF pin with hysteresis function

Built in thermal shutdown function

Built in current limit function

Available in TO-220,TO-263 packages

Applications

LCD Monitor and LCD TV
