White-LED flash driver maximizes image quality
The ADP1655 dual white-LED flash driver maximizes the limited current available in battery-operated digital cameras to increase flash brightness to over 200 lumens and improve picture quality. The inductor-based driver improves the reliability of high-resolution camera operation in cell phones, digital still cameras, camcorders, PDAs and other camera-equipped portable devices, particularly in dark environments.
The device integrates a 2-MHz synchronous boost converter, a 500-mA programmable current source, and an I2 C interface. Housed in a 12-ball WLSCP, the part also offers a –40 to 125°C temperature range, a 5% flash-current accuracy, and a high-side current source. ($0.95 ea/1,000 — available now.)
