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.
Applications
n LED Lighting
n Boost constant current driver
n Monitor LED Backlighting
n 7to 15LCD Panels

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. XL6005 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.
