ADI manufactured ADP1650 1500-mA white LED driver.

It features like a programmable I²C-compatible interface, programmable torch and flash currents for one LED up to 1500 mA, two independent TxMASK1 inputs and a 4-bit ADC.

It provides high efficiency at 85 percent at the typical battery voltage (90 percent peak). The ultra-compact ADP1650 measures only 2 mm × 1.5 mm in a 12-ball WLCSP package and reduces PCB requirements.

It enables a complete high power flash design in less than 17 mm2 by integrating a programmable 1.5-MHz or 3.0-MHz synchronous inductive boost converter, a tiny, 1-mm high, low-cost, 1-μH power inductor, and 0603 case-size input and output capacitors.

The new LED driver operates efficiently over the entire battery voltage range by maximizing the input-power-to-LED-power conversion and minimizing battery current draw during flash events. Designed to operate using the limited battery current available for flash, the ADP1650 connects easily to the latest image sensors and image processors to provide excellent picture quality in low ambient light environments.
