This application note describes a proprietary solution that will drive LEDs off a 12VAC input for MR16 and similar retrofit lamps. This design can be used with both magnetic and electronic transformers. It is dimmable with leading-edge dimmers for magnetic transformers and with trailing-edge dimmers for electronic transformers. No electrolytic capacitors are required. This greatly extends the lifetime of an LED lamp, because electrolytic capacitors are typically the element of the system with the shortest lifetime.
