Description
General part information
ADP1660 Series
The ADP1660 is a very compact, highly efficient, dual white LED flash driver for high-resolution camera phones that improves picture and video quality in low light environments. The device integrates a programmable 1.5 MHz or 3.0 MHz synchronous inductive boost converter, an I2C-compatible interface, and two 750 mA current sources. The high switching frequency enables the use of a tiny, 1 mm high, low cost, 1 μH power inductor, and the parallel current sources permit LED cathode grounding for thermally enhanced, low EMI, and compact layouts.The LED driver maximizes efficiency over the entire battery voltage range to maximize the input-power-to-LED-power conversion and minimize battery current draw during flash events.The LED driver maximizes efficiency over the entire battery voltage range to maximize the input-power-to-LED-power conversion and minimize battery current draw during flash events. A programmable DC battery current limit safely maximizes LED current for all LED VFand battery voltage conditions.A TxMASK input permits the flash LED currents and battery current to reduce quickly during a power amplifier current burst. The I2C-compatible interface enables the programmability of timers, currents, and status bit readback for operation monitoring and safety control.ADP1660 comes in a compact 12-ball, 0.5 mm pitch package and operates within specification over the full −40°C to +125°C junction temperature range.APPLICATIONSCamera-enabled cellular phones and smart phonesDigital still cameras, camcorders, and PDAs
