LOW DROPOUT VOLTAGE LINEAR LED DRIVER IC IN SOT26
The BCR430U is a monolithically integrated linear LED controller
designed to function as a Constant Current Regulator (CCR) for linear
LED driving. The device operates over a voltage range from 5V to
42V and regulates the output LED current up to 100mA, set by an
external resistor. It is designed for driving LEDs in strings and will
reduce current at increasing temperatures to self-protect. The low
voltage drop during current regulation allows efficient driving of LED
strings with a range of forward voltages and supply voltage
