XL6001
400KHz 32V 2A Switching Current Boost LED Constant Current Driver
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.
n Wide 3.6V to 24V Input Voltage Rang
n 0.22V Constant Current Sense Voltage
n Directly drive 3~8 Series 1W LED
n Fixed 400KHz Switching Frequency
n Max. 2A Switching Current Capability
n Up to 92% efficiency
n Excellent line and load regulation
n EN PIN TTL shutdown capability
n Internal Optimize Power MOSFET
n Built in LED Open Protection
n Built in Soft-Start Function
The XL6001 could directly drive 5~8 Series 1W
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.
