Description:

4-Channel LED Driver

Features

* Drive Common Anode or Common Cathode LEDs
* Low 50mV Dropout at 20mA
* 20mA full scale current

Applications

* significantly improved efficiency. The BCT3221 requires only a 50mV dropout voltage at a 20mA load on each output to match the LED brightness. By using one SEL pin, the BCT3221 can support to drive 4 parallel Co-Anode or Co-Cathode white LEDs and regulates a constant current for uniform intensity.
