1. An energy regulation circuit coupled to a transmission path and comprising:

  • a first voltage regulator adjusting an input voltage to generate an adjustment voltage;

    a first energy accumulator charged according to the input voltage or the adjustment voltage;

    a first switch coupled to the first energy accumulator;

    a second energy accumulator coupled to the first switch, wherein when the first switch is turned on, the second energy accumulator is connected to the first energy accumulator in parallel;

    a second voltage regulator configured to generate an operation voltage according to a voltage stored in the first energy accumulator when the first switch is turned off, and configured to generate the operation voltage according to a sum of the voltage stored in the first energy accumulator and a voltage stored in the second energy accumulator when the first switch is turned on; and

    a controller communicating with a host device and a peripheral device according to the operation voltage, wherein the controller controls the first switch,wherein;

    responsive to the peripheral device is a charger, the controller controls the transmission path to transmit a charging voltage provided by the charger to the host device, andresponsive to the peripheral device is not the charger, the controller controls the transmission path to transmit a host voltage provided by the host device to the peripheral device.
