The XL6001 regulator is fixed frequency PWM
Boost (step-up) LED constant
current
driver,
capable of driving Series 1W 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 XL6001 could directly drive 5~8 Series I W
LED units at VIN>12V .
The PWM control circuit is able to adjust the
duty ratio linearly from 0 to 90%. An enable
function, an over current protection function
is built inside. An internal compensation
block is built in to minimize external
component count.
