Description
8 Channel Constant Current LED Driver

Features

* Low 50mV Dropout at 20mA

Applications

* significantly improved efficiency. The BCT3258 requires only a 50mV dropout voltage at a 20mA load on each output to match the LED brightness. Users can easily configure the LED current from 1.25mA to 20mA by a serial pulse interface. The dimming of white LEDs current can be achieved by applying a
