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.

Description
Ground Pin.
Enable Pin. Drive EN pin low to turn off the device, drive it
high to turn it on. Floating is default high.
Power Switch Output Pin (SW).
Supply Voltage Input Pin. XL6004 operates from a 3.6V to
32V DC voltage. Bypass Vin to GND with a suitably large
capacitor to eliminate noise on the input.
Feedback Pin (FB). The feedback threshold voltage is 0.22V.
