BCT3222 Description

The BCT3222 is a high performance white LED driver. The BCT3222 uses an internal resistor to set the bias current for four LEDs, which are matched to +/-1.5%. The BCT3222'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.
