BCR420UFD - LINEAR LED CONSTANT CURRENT REGULATOR
The BCR420UFD and BCR421UFD monolithically integrate transistors, diodes and resistors to function as a Constant Current Regulator (CCR) for linear LED driving.
The device regulates with a preset 10mA nominal that can be adjusted with an external resistor up to 350mA.
It is designed for driving LEDs
