AL8843SP-13 Description

Short technical summary and product information.

The DIODES™ AL8843SP-13 is a hysteresis mode DC-DC step-down converter designed for efficiently driving single or multiple series-connected LEDs. It operates from an input supply voltage ranging from 4.5V to 40V and can provide an externally adjustable output current up to 3A, supporting up to 60W of output power.

 

Key features include an internal 40V NDMOS power switch, typical 4% output current accuracy, and a single pin for on/off and brightness control via DC voltage or PWM signals. The device supports soft-start, LED short protection, and over-temperature protection. Its high efficiency, up to 97%, makes it suitable for various lighting applications.

 

The AL8843SP-13 is available in an 8-SO-EP package with a surface mount type. It is designed for applications such as LED retrofits for low voltage halogen, low voltage industrial lighting, LED backlighting, and illuminated signs.
