... Constant current LED driver with 3.0V to 5.5V supply voltage Description The CS8808 is a 8-Bit constant current LED driver IC which is designed for LED displays. The output current can be adjusted by using an external resistor. All outputs will have the same current drive level which is crucial in LED display application. This driver has built-in 8-bit constant current outputs, a 8-bit shift register, and a 8-bit latch circuit ...
