General Description
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. An internal compensation
block is built in to minimize external
component count.
