The ADP1655ACBZ-R7 from Analog Devices is a highly efficient, dual white LED flash driver designed for camera-enabled devices. It integrates a 2 MHz synchronous boost converter and an I2C-compatible interface, enabling programmability of currents, timers, and status readbacks.
This device can drive LEDs with currents up to 400 mA for two LEDs or 500 mA for a single LED in flash mode, with 5% accuracy. In torch mode, it supports currents up to 160 mA with 10% accuracy. The high switching frequency allows for a tiny 2.2 μH power inductor, contributing to its ultracompact solution.
Key features include safety functions such as thermal overload protection, flash timeout, inductor fault detection, output overvoltage, and short circuit protection. The ultracompact 2 mm × 1.5 mm 12-ball WLCSP package makes it suitable for space-constrained applications like camera phones, digital still cameras, camcorders, and PDAs.
With a peak efficiency of 88%, the ADP1655ACBZ-R7 minimizes battery current draw during flash events. It operates within an input voltage range of 2.5V to 5.5V and has an operating temperature range of -40°C to 85°C.
