General Description

The BCT3228 is a high performance 8 channel white LED driver.

The BCT3228 uses two internal resistor to set the bias current for four LEDs.

The BCT3228'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.
