The ADP1655 is a very compact, highly efficient, dual white LED flash driver for high resolution camera phones, which improves picture and video quality in low light environments. The device integrates a 2 MHz synchronous inductive boost convertor, an I2C-compatible interface and a 500 mA current source. The high switching frequency enables the use of a tiny, low profile 2.2 μH power inductor, and the current source permits LED cathode grounding for thermally enhanced, low EMI and compact layouts.
