BCT3364 4 Channel LED Driver With Digital Pulse Brightness Control 4 Channel LED Driver With Digital Pulse Brightness Control GENERAL DESCRIPTION The BCT3364 is a high performance white LED driver. The BCT3364 uses an internal resistor to set the bias current for four LEDs, which are matched to 1.5%. The BCT3364's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower dropout voltage, and in some applications, significantly improved efficiency. The BCT3364 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...
