Tricolor LED Driver for LCD Backlighting in Portable Devices

摘要

ON Semiconductor has introduced the NCP5623, a high-efficiency, triple-output LED driver with PC interface and built-in gradual dimming. The device is specifically designed to drive tricolor RGB (red, green, blue) LEDs for fun lighting or enhanced LCD backlighting in portable applications such as cell phones and MP3 players. Offered in the compact LLGA-12 package, the NCP5623 is the smallest RGB LED charge pump driver housed in a non-bump plastic package on the market today.
