NCP5623C
Triple Output I2C Controlled
RGB LED Driver
The NCP5623C mixed analog circuit is a triple output LED driver
dedicated to the RGB illumination or backlight LCD display.
The builtin DC/DC converter is based on a high efficient charge
pump structure with operating mode 1x and 2x. It provides a 94% peak
efficiency. The tiny package makes the device suitable for room
limited portable applications.
