Abstract: A power circuit includes a bleeder circuit, wherein a first terminal of the bleeder circuit is an output terminal, and a second terminal of the bleeder circuit is grounded; a control circuit, wherein a first terminal of the control circuit is connected to the output terminal, a second terminal of the control circuit is a feedback terminal and is connected to the bleeder circuit, and a third terminal of the control circuit is an input terminal; and a feedback capacitor, wherein a first terminal of the feedback capacitor is connected to the output terminal, and a second terminal of the feedback capacitor is connected to the bleeder circuit. The power circuit adds a feedback capacitor between the output terminal and the feedback terminal and can rapidly provide output terminal voltage changes to the feedback terminal and accelerate regulation of an output voltage.
