General Description

The XL6004 regulator is fixed frequency PWM

Boost (step-up) LED constant current driver,

capable of driving Series 1W/3W LED units with

excellent line and load regulation. The regulator is

simple to use because it includes internal frequency

compensation and a fixed-frequency oscillator so

that it requires a minimum number of external

components to work.

The XL6004 could directly drive 12 Series 1W LED

units at VIN>12V.

The PWM control circuit is able to adjust the

duty ratio linearly from 0 to 95%. An enable

function, an over current protection function

is built inside. An internal compensation

block is built in to minimize external

component count.
