AMG-LL75x
High Efficiency Step Down LED Driver for High Brightness LED and OLED
1. Functional Description of the AMG-LL75x
The AMG-LL75x is a family of point-of-load regulator for LED lighting applications. By
providing a highly efficient constant current regulation off a DC source the AMG-LL75x is
perfectly suited for applications that require low DC levels for safety reasons, driving multiple
LED groups in one luminaire, mobile or in-vehicle lighting, and to refit existing low voltage
halogen installations.
