Datasheet	LN2140-natlinear.pdf

s The LN2140 regulator is fixed frequency PWM boost LED constant current driver, capable of driving series 1W/3W LED units with excellent line and load regulation. The LN2140 regulator includes internal frequency compensation and fixed-frequency oscillator. An over current protection function is built inside. So the regulator requires a minimum number of external components to work. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 90%. The LN2140 is available in SOP8.
