If a large-capacity capacitor is directly used, the startup time is affected due to long charging time in the power-on process. Therefore, the buffering fast discharging circuit shown in fig. 7 is designed to solve the problem of slow capacitor charging in the power-on process during the power-on process, and meanwhile, it can be ensured that the capacitor is rapidly discharged in the power-off process, and the power loss is not affected, specifically, the motherboard power supply circuit can be arranged between the motherboard power supply and the main control chip 200, referring to fig. 7, the motherboard power supply circuit includes:
the energy-saving circuit comprises a first isolation resistor R3, a second isolation resistor R4, a first energy-storing capacitor C2 and a diode D;

In addition, in order to ensure the power supply quality, one or more filter capacitors C1, such as the filter capacitor C3 and the filter capacitor C4 shown in fig. 7, may be disposed in the motherboard power supply circuit.
Wherein, C1 is an energy storage capacitor; the two resistors R1 and R2 are isolation resistors and play a role in slow charging; the diode D may be a schottky diode to provide a discharge loop; c3 and C4 are filter capacitors for filtering noise. The working process of the circuit is as follows:
when the power is on, VCC _ IN can directly supply power to the mainboard, the node B instantly reaches VCC _ IN level, and the mainboard starts working. Meanwhile, VCC _ IN slowly charges the capacitor C2 through the resistors R1 and R2, the level of the node A is slowly increased and finally rises to VCC _ IN, and the charging of the capacitor C2 is finished. In the charging process, the cathode level of the diode D is higher than the anode pin level, and the diode is not conducted.
When the power is off, VCC _ IN loses the external power supply, and the level of the node B is gradually reduced until the level is lower than the level of the node A. At this time, the diode D is turned on, and the electric energy stored in the capacitor C2 is released to the main board through the diode D.
