Abstract

A power supply circuit for a dimmer switching device includes a voltage doubler circuit, a filter circuit, a switching power supply, and a linear regulator circuit. In one embodiment, the voltage doubler circuit includes a first stage having a first capacitor and a first diode, and a second stage having a second capacitor and a second diode. The switching power supply may include a feedback circuit, and may be a non-isolated power supply. In an embodiment, the dimmer device is variable between an OFF position and a full ON position, and the circuit is effective to provide power for operation of the switching power supply while the dimmer device is in the full ON position.
