General Description

The XL7005 is a 150KHz fixed frequency

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

capable of driving a 0.4A 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

frequency compensation and a

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 output short protection

function happens, the operation frequency

will be reduced from 150KHz to 45KHz. An

internal compensation block is built in to

minimize external component count.
