BCR420UW6 / BCR421UW6 LINEAR LED CONSTANT CURRENT REGULATOR IN SOT26 Description The BCR420UW6 and BCR421UW6 monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear LED driving. Each device regulates with a preset 10mA nominal that can be adjusted with an external resistor up to 350mA. 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 multiple applications, as long as the maximum supply voltage to the device is < 40V. With low-side control, the BCR421U has an Enable (EN) pin which...
