METHOD AND APPARATUS FOR TRIAC APPLICATIONS

摘要

Aspects of the disclosure provide a circuit. The circuit includes a control circuit and a return path circuit. The control circuit is configured to operate in response to a first conduction angle of a dimmer coupled to the circuit. The first conduction angle is adjusted to control an output power to a first device. The dimmer has a second conduction angle that is independent of the control of the output power to the first device. The return path circuit is configured to provide a return path to enable providing power to a second device in response to the second conduction angle.
