When one control signal is low level, second control signal is high level；And the switching of first control signal and second control signal
There is the time difference in the process, voltage stabilization when ensuring to switch transition.Illustratively, electric when needing voltage conversion unit to export 5V
When pressing signal, second control signal is high level, and first control signal is low level；When needing to export 9V or 12V voltage signal
When, first control signal is high level, and second control signal is low level, so that load switch is connected, and voltage conversion unit
It closes, that is, stops working.However, the application does not limit this.In other implementations, load switch and voltage conversion are single
