The ADM8843 uses charge pump technology to provide the power to drive up to four LEDs.

The LEDs are used for backlighting a color LCD display that has regulated constant current for uniform brightness intensity.

The main display can use up to three LEDs, and the sub display uses one LED.

Drives 4 LEDs from a 2.6 V to 5.5 V (Li-Ion) input supply 1×/1.5×/2× fractional charge pump to maximize power efficiency 0.3% typical LED current matching Up to 88% power efficiency over Li-Ion range Powers main and sub display LEDs with individual shutdown Package footprint only 9 mm2 (3 mm × 3 mm) Package height only 0.55 mm Low power shutdown mode Shutdown function Soft start limiting in-rush current.
