Switching control circuit and control method
A switching control circuit for controlling a multi-channel switching circuit having switching circuits, input terminals coupled to input voltage signals, and an output terminal for providing an output voltage signal, can include: a logic control circuit configured to receive an external operation signal and a first single pulse signal, and to generate an enable signal, a trigger signal, and feedback control signals; a reference voltage regulation circuit configured to receive the enable signal, the trigger signal, and a maximum one of the input voltage signals, and to generate a reference voltage signal; and feedback circuits corresponding to the switching circuits, where the plurality of feedback circuits are configured to receive the feedback control signals, a minimum one of two input voltage signals that are participating in the switching operation, the reference voltage signal, and the output voltage signal, and to generate switching control signals for controlling the switching circuits.
