Datasheet

XL1507

3A 150KHz 40V Buck DC to DC Converter

Features

General Description

n Wide 4.5V to 40V Input Voltage Range

n 3.3V,5V,12V, and adjustable versions

n Output Adjustable from 1.23V to 37V

The XL1507 is a 150 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

Maximum Duty Cycle 100%

Minimum Drop Out 1.5V

load regulation. Requiring

minimum

n Fixed 150KHz Switching Frequency

n 3A Constant Output Current Capability

n Internal Optimize Power Transistor

number of external components, the regulator

is simple to use and include internal

frequency

compensation

and

High efficiency

Excellent line and load regulation

TTL shutdown capability

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. When second current limit

function happens, the operation frequency

will be reduced from 150KHz to 50KHz. 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

Built in second current limit function

Available in TO-252 package

Applications

n LCD Monitor and LCD TV

n Digital Photo Frame

n Set-up Box

n ADSL Modem

n Telecom / Networking Equipment
