The CXLE8116 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 CXLE8116 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
