BCT3258 Overview
The BCT3258 is a high performance constant current white LED driver. The BCT3258 uses an internal resistor to set the bias current for 8 LEDs, which are matched to 3%. The BCT3258'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.
