发明名称	INPUT SELF-ADAPTIVE SWITCHING POWER SUPPLY
摘要	An input self-adaptive switching power supply, comprising an input interface (10), a control circuit (20), a switching circuit (30) and a DC/DC converter (40). The switching circuit comprises a PFC converter (31). The control circuit is configured to sample a voltage signal accessed by the input interface and output according to the voltage signal a corresponding control signal to the switching circuit. The input interface is used to access an alternating current (AC) or direct current (DC) high-voltage signal. The switching circuit is used to select, according to the control signal, between directly outputting the voltage signal accessed by the input interface to the DC/DC converter, or outputting the voltage signal to the PFC converter first and then outputting to the DC/DC converter. The input self-adaptive switching power supply can reduce a loss and improve an efficiency, realizing an optimal efficiency of the power supply in different input systems.
