An Integrated 350V Dimmer


The design of an almost fully integrated phase-cut dimmer is presented. The circuit was designed on a 1um ultra high voltage (UHV) MOS technology in a silicon-on-insulator (SOI) wafer. The dimmer can operate with a duty cycle of up to 95% power (80%) and a load of up to 100 W which is adequate for modern domestic dimmable LED lights. The total occupied silicon area is 6.5 mm 2 without pads.
