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.
