DiodesZetex BCR405UW6Q-7 LED Driver IC, 40 V 100mA 6-Pin SOT-26

The DiodesZetex monolithically integrates a transistor, diodes, and resistors to function as a Constant current Regulator (CCR) for LED driving. The device regulates with a preset 50mA nominal that can be adjusted with 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 components, this CCR is fully integrated into an SOT26, minimizing PCB area and component count.

LED Constant current regulator Using PNP Emitter follower with Emitter resistor to current limit Constant current (Preset) of 50mA at ± 10% IOUT up to 100mA adjustable with an external resistor 40V Supply voltage and PD of up to 1W in SOT26 LED dimming using PWM up to 25kHz
