The FAN5332A is a high efficiency, high current serial LED driver and OLED supply with a 30V integrated switch.
The FAN5332A is a serial LED driver designed for handheld communications equipment, flash LEDs, and display bias applications. It operates at a fixed 1.5 MHz switching frequency, provides up to 1.5 W output power, and features low shutdown current (<1 µA) and cycle‑by‑cycle current limiting for extended battery life.
The datasheet includes pin assignments, absolute maximum ratings, electrical characteristics, typical performance curves, and layout recommendations. It also lists recommended external components such as inductors, capacitors, and Schottky diodes, and provides mechanical dimensions for the 5‑lead SOT‑23 package.
