Design of a Triac Dimmable LED Driver Based on SSL2101 T
摘要
Abstract
A Triac dimmable LED driver based on SSL 2101 T is designed.The driver based on flyback topology with an extra Triac dimmer and a 220V/50Hz mains input achieves flicker free,smooth dimming.The proposed driver has acceptable efficiency and power factor.The Triac dimmer and the driver are introduced and the dimming control theorem is analyzed.The design of the transformer is demonstrated in details.Experimental results show that the full load efficiency of a demo board is 73%,power factor 0.762 and the dimming range from 0 to 347.7mA.关键词
