Triple Output LED Driver
ON Semiconductor introduces its NCP5623, a high efficiency triple output LED driver with I2C interface and built-in gradual dimming. The device is 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 LLGA-12 package, it is a small RGB LED charge pump driver housed in a non-bump plastic package. This LED driver performs autonomous operations upon the command of the processor via its I2C interface. Its three independently controlled current outputs (with ± 0.5 percent typical matching tolerance and 32 current levels) allow the display of more than 32,000 colors with a tricolor RGB LED.
