Abstract
A power circuit includes a first switch, a second switch, and a driving circuit. A first terminal of the first switch is configured to receive an input voltage. A first terminal of the second switch is coupled to a second terminal of the first switch, and a second terminal of the second switch is configured to be coupled to a ground. The driving circuit receives a PWM control signal, and provides a first driving signal to a control terminal of the first switch and a second driving signal to a control terminal of the second switch based on the PWM control signal. The driving circuit determines whether the PWM signal is at a high impedance logic level. When the PWM signal is at the high impedance logic level, the driving circuit regulates a voltage of the second driving signal such that the second driving switch operate in linear region.
