Patent attributes
A circuit is described for powering a video doorbell in signal communication with a chime that outputs audio in response to a button on the video doorbell being pressed. The circuit includes a rectifier circuit configured to: i) receive a first voltage signal generated based on a power source and ii) generate a second voltage signal based on the first voltage signal. The circuit includes a boost circuit that generates a high-voltage direct-current (DC) signal for charging a capacitor without generating a peak current that triggers a particular noise output from the chime. The circuit also includes a converter circuit that generates a low-voltage power signal based on the high-voltage DC signal and a charge stored at the capacitor. The low-voltage power signal is for powering a plurality of components of the video doorbell.
