General Description

The BCT3220 is a high performance white LED driver.

The BCT3220 uses an internal resistor to set the bias current for four LEDs, which are matched to 1.5%.

The BCT3220'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.
