Datasheet Summary
20 to 100mA LED CONSTANT CURRENT REGULATOR in SOT26 (SC74R)
Description
The BCR402UW6 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 an external resistor up to 100mA. It is designed for driving 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.
With no need for additional external ponents, this CCR is fully integrated into SOT26 (SC74R) minimizing PCB area and...
