    摘要: An exemplary power supply control circuit (200) includes a first port (201), a second port (202), a third port (203), a controllable switch (280), and a control circuit (270). The first and second ports are configured to receive a power supply voltage signal. The second and third ports are configured to output the power supply voltage signal to a load circuit. The controllable switch includes a control member (281) and a switch member (282). The control circuit is configured to control a working state of the control member. When the load circuit stops working, the control circuit controls the control member to control the switch member to be disconnected, so as to cut off the power supply voltage signal from outputting to the load circuit.

    摘要: An exemplary multiplexed DC voltage regulation output circuit (2) comprises a first output circuit, a second output circuit, a transformer (21), a power control chip (22), a feedback circuit (20), and a control circuit (26). The first output circuit is configured for outputting low voltage. The second output circuit is configured for outputting high voltage. The transformer is configured for outputting voltages to the first output circuit and the second output circuit. The feedback circuit feeds composite signals from the first output circuit and the second output circuit back to the power control chip. The power control chip adjusts the output voltages of the transformer by changing impulse width of voltages transmitted into the transformer in accordance with the composite signals. The control circuit controls the output voltage of the second output circuit back to a normal high voltage when the output voltage is higher than normal.
