The supplemental circuit includes a detection circuit producing input signals, a switch, a signal generation circuit producing a control signal controlling the switch's open and close according to the input signals, and a RC circuit. When the switch is closed, the PMIC and the RC circuit are series-connected to ground. The supplemental circuit resolves the reduced performance of the PMIC due to the field effect transistors (FETs) inside the PMIC suffering greater switching loss when the PMIC is constantly series-connected to ground through RC circuit.
