Dual 750 mA LED Flash Driver with I2C-Compatible Interface
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 VF and 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.APPLICATIONS
