Datasheet Summary
LN2141 c40V 3A Boost LED Constant Current Driver
- General Description
The LN2141 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 LN2141 regulator includes internal frequency pensation and fixed-frequency oscillator. An over current protection function is built inside. So the regulator requires a minimum number of external ponents to work. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 90%. The LN2141 is available in SOP8 packages.
