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.
