Description

The BCR402UW6Q monolithically integrates a transistor, diodes and resistors to function as a Constant Current Regulator (CCR) for LED driving. The device regulates with a preset 20mA nominal that can be adjusted with external resistor up to 65mA. It is designed for driving 0.25W LEDs in strings and will reduce current at increasing temperatures to self-protect. Operating as a series linear CCR for LED string current control it can be used in applications with supply voltages up to 40V.
