AC LED Driver ICs, High Power + PFC


 To achieve the versatility and controllability promised by LEDs, they must be intelligently driven. With a family of proven mains AC LED driver and controller ICs, we helps simplify lamp design, extend lifetime and reliability, and with the smallest form factor.

we has a respected and long-standing tradition of delivering integrated driver solutions for conventional light sources. Combining our extensive systems knowledge in areas where SSL is finding favor, such as photo flash and LCD backlighting, with our proven AC/DC SMPS technology creates an outstanding family of mains AC driver ICs for LED applications. Our 2nd generation solutions help you deliver lighting products with lower energy consumption, longer lifetimes, smaller form factors, increased robustness and improved intelligence. A family approach that uses the same controller architecture ensures you can easily apply similar products across your LED lighting portfolio – no matter whether that is external ballasts or retrofit lamps and isolated or non-isolated configurations.

Easy integration

All our solutions integrate easily into products – so designers don't need to have extensive electronics skills. This 'hassle-free' integration cuts time-to-market and will help speed the adoption of LED in the general lighting market.

Reducing your design effort

Helping reduce your design effort, we offer reference boards and evaluation kits for many of our lighting control and driver ICs. In addition online design tools are available for our SSL152x and SSL210x families.
