ANGSEMI AS6533 Flash LED Driver IC Datasheet
The AS6533 is a 3 MHz fixed‑frequency synchronous boost converter optimized for flash LED and movie‑mode applications. It provides adaptive regulation, high efficiency, and multiple protection mechanisms such as over‑voltage, over‑temperature, and cycle‑by‑cycle current limiting.
Key features include two logic inputs for flash and movie modes, independent current setting via external resistors, a soft‑start to limit inrush, and a shutdown current below 1 µA. The device is supplied in a 14‑pin 2 mm × 3 mm DFN package and operates from 2.7 V to 5.0 V across –40 °C to +85 °C.
