ON Semiconductor, global supplier of efficient power management solutions, has expanded its LED portfolio with the addition of two dual output white LED drivers for handheld and consumer applications. Offered in the tiny 2.0 mm x 2.0 mm x 0.55 mm LLGA-12 package, the NCP5602 and NCP5612 are the dual output charge pumps for driving LCD display backlighting. Each device achieves up to 87 percent peak efficiency with 0.2 percent LED-to-LED matching, thus assuring matched and consistent brightness.
The NCP5602 and NCP5612 have a built-in ICON function that drives a low current through one of the two LEDs, allowing the clock display to be seen even in a dark environment. This dimming mode eliminates the need for additional software programming and simplifies overall design. To ensure safe operation without adding extra components, the NCP5602 and NCP5612 feature short-circuit and overvoltage protection.
Hyung-Sup Kim, director for the consumer products division, said, ON Semiconductor, "As LED technology and brightness improves, small handheld LCD displays will require fewer white LEDs for backlighting. The new white LED drivers we are introducing are the smallest dual LED boost drivers on the market today. The fully protected and integrated NCP5602 and NCP5612 highlight ON’s commitment to developing and delivering smaller, more functional devices for power management in portable devices."
