Abstract
An audio/video (A/V) recording and communication doorbell device includes a transistor assembly and control circuitry. The transistor assembly is electrically coupled between an input power bus that distributes alternating current (AC) input power and/or direct current (DC) input power, and an output power bus that provides a DC output power for the A/V recording and communication doorbell device. The control circuitry is configured to cause the transistor assembly to convert AC input power and/or DC input power from the input power bus to the DC output power into the output power bus, to provide the DC output power for the A/V recording and communication doorbell device.
