Analog Devices ADP1655 Dual LED Flash Driver Datasheet
The ADP1655 dual LED flash driver is designed for camera‑enabled mobile phones, digital cameras and camcorders. It integrates a 2 MHz synchronous boost converter, an I2C‑compatible control interface and a high‑efficiency LED current source, allowing up to 500 mA flash current for a single LED or 400 mA for two LEDs. The device is packaged in a 12‑ball 0.5 mm pitch WLCSP and operates from 2.7 V to 5.5 V input voltage.
The datasheet provides detailed specifications, pin descriptions, timing diagrams, safety features such as thermal shutdown at 150 °C and over‑voltage protection, as well as recommended external component values and PCB layout guidelines to ensure low EMI and reliable operation.
