Skyworks introduces the SKY81298 triple channel LED flash driver. The SKY81298 is optimized for LED flash applications implementing tri-tone flash LED color compensation, or dual rear LED flash, plus single front LED flash to support “selfie” pictures taken from the front-facing camera.
It is ideally suited for small battery-powered applications, including smartphones and tablets. Independent GPIO or I2C interfaces support any customer control requirement. The SKY81298 actively monitors battery/system voltage and reduces flash current automatically to avoid system brownout, allowing the flash to operate over a wider (lower) battery range.
The compact 3.62 mm2 device is provided in a 16-bump, 1.903 x 1.903 x 0.605 mm wafer-level chip scale package (WLCSP).
