BCT3221 - 4-Channel LED Driver

The BCT3221 is a high performance white LED driver. The BCT3221 uses an internal resistor to set the bias current for four LEDs, which are matched to +/-1.5%. The BCT3221's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower dropout .

BCT3221 Features

* Drive Common Anode or Common Cathode LEDs

* Low 50mV Dropout at 20mA

* 20mA full scale current
