主要应用
概述
The Silergy SSL2129AT is a high-efficiency controller IC for superior dimmable LED lighting solutions that typically operates in the lamp power range of 4 to 25 W. The straightforward design produces a cost-effective yet compact application, suitable for use with GU10 and PAR16 formats. A low-cost bipolar bleeder circuit supports a best-in-class dimmer compatibility performance for mainstream, single-stage LED driver applications. The SSL2129AT can be configured in either buck (non-isolated) or flyback (isolated) topologies at mains supply voltages of 100 to 120 V or 230 V.
Applications
- Dimmable retrofit LED lamps
- Dimmable driver modules for LED lighting
