Digi-Key Launches New LED Driver

Digi-Key has launched High-efficiency HB offline LED driver CPC9909. It uses a proprietary high-voltage BCDMOS on SOI process.

The driver has an internal regulator that allows it to operate from 8VDC to 550VDC . The CPC9909 features pulse frequency modulation with a constant peak-current control scheme.

LED dimming can be implemented by applying a small DC voltage to the LD pin or by applying a low frequency PWM signal to the PWMD pin.

It can be available in flat-panel display RGB backlighting, signage and decorative LED lighting, and DC-DC or AC/DC LED drivers.
