Abstract:
A USB interface power supply method and power supply device for a time division multiple access load system reduce costs of using the capacitance while guaranteeing the performance. The USB interface power supply device includes: a USB interface, a soft-start circuit and a DC-DC direct current conversion circuit that are connected in sequence, wherein, an output of the DC-DC direct current conversion circuit supplies power to the time division multiple access load system. The power supply device also includes a capacitor, wherein: a first end of the capacitor is connected between the soft-start circuit and the DC-DC direct current conversion circuit, a second end of the capacitor is set to be grounded, and the capacitor is used for limiting an input current of the DC-DC direct current conversion circuit.
