General Description

The XL1530 is a 380KHz 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

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 short protection function

happens, the operation frequency will be

reduced from 380KHz to 80KHz. An internal

compensation block is built in to minimize

external component count.
