Dual LED Flash Driver with I2C Compatible Interface
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.
This designates products ADI does not recommend broadly for new designs.
The motherboard features a 3.3 V regulator and two adjustable regulators, one for VDDIO and one for ADP1655 supply voltage (VIC). The daughterboard contains numerous jumpers and test points for easy evaluation of the board.
