A8530 Datasheet Ultracompact 6-Channel Backlight and Flash/Torch White LED Driver

Manufacturer: Allegro MicroSystems

Overview: A8530 Ultracompact 6-Channel Backlight and Flash/Torch White LED.

General Description

The A8530 high efficiency charge pump ICs offer a simple, low-cost white LED driver solution for driving four display backlight and two flash/torch/video mode white LEDs.

Using a proprietary control scheme (1×, 1.5×, and 2×), the A8530 can deliver well-matched LED current while maintaining the highest efficiency and low EMI.

The LED current is regulated over the entire range of Li+ battery voltage to provide uniform intensity.

Key Features
