Product Description

Product Details
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.
The efficiency is high over the entire battery voltage range to maximize the input power to LED power conversion and minimize battery current draw during flash events. In addition, a Tx-mask input permits the flash LED current to reduce quickly and, therefore, the battery current reduces quickly, during a GSM power amplifier current burst.
The I2C-compatible interface enables the programmability of timers, currents, and status bit readback for operation monitoring and safety control.
The ADP1655 comes in a compact 12-ball 0.5 mm pitch WLCSP package and is specified over the full −40°C to +125°C junction temperature range.
**Applications**
* Camera-enabled cellular phones and smart phones
* Digital still cameras, camcorders, and PDAs
