The MOS transistor Q1 is placed on the negative voltage input end of the DC/DC power supply module. At the moment of power-on, the level of the first pin of the DC/DC power supply module is the same as the fourth pin, and then the control circuit reduces it to the negative voltage at a certain rate. , the speed of the voltage drop is determined by the time constant C2*R2, and this slope determines the maximum inrush current. D1 is a Zener diode used to limit the gate-source voltage of the MOS transistor Q1. Components R1, C1 and D2 are used to ensure that the MOS transistor Q1 remains off when it is just powered on.
