A system includes a converter and a regulator. The converter supplies power to a load circuit during an active mode to power first and second devices in the load circuit. The converter is OFF during an inactive mode. The regulator supplies power to the load circuit during the inactive mode to operate the first device in an active state and regulates a power supply voltage, supplied during the inactive mode, to a predetermined voltage. The power supplied during the inactive mode is less than an amount of power to operate the first and second devices in an active state. During the inactive mode, the regulator increases the power supply voltage to a voltage greater than the predetermined voltage to prevent the power supply voltage from decreasing to a voltage less than the predetermined voltage due to an increased amount of load as a result of turning ON the second device. |
