General Description
The XL6006 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 XL6006 could directly drive 16 Series
1W/3W LED units at VIN=24V .
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.
Applications
n LED Lighting
n Boost constant current driver
n TFT LED Backlighting

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. XL6006 operates from a 5V 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.
