400KHz 32V 2A Switching Current Boost LED Constant Current Driver
XL6001
Features
General Description
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 1W
LED units at VIN>12V .
Wide 3.6V to 24V Input Voltage Rang
0.22V Constant Current Sense Voltage
Directly drive 3~8 Series 1W LED
Fixed 400KHz Switching Frequency
Max. 2A Switching Current Capability
Up to 92% efficiency
Excellent line and load regulation
EN PIN TTL shutdown capability
Internal Optimize Power MOSFET
Built in LED Open Protection
Built in Soft-Start Function
Built in Frequency Compensation
Built in Thermal Shutdown Function
Built in Current Limit Function
Available in SOP8 package
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
LED Lighting
Boost constant current driver
Monitor LED Backlighting

Description
Enable Pin. Drive EN pin low to turn off the device, drive it
high to turn it on. Floating is default high.
Supply Voltage Input Pin. XL6001 operates from a 3.6V to 24V
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.
No Connected.
Power Switch Output Pin (SW). Output is the switch node that
supplies power to the output.
Ground Pin.
