General Description

The XL4015 is a 180 KHz fixed frequency

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

capable of driving a 5A 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 over

current protection function is built inside.

When short protection function happens, the

operation frequency will be reduced from

180KHz to 48KHz. An internal compensation

block is built in to minimize external

component count.
