The XL6005 regulator is fixed frequency PWM

Boost (step-up) LED constant current driver,

capable of driving Series 1W/3W/5W 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 XL6005 could directly drive 11 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.
