Zusammenfassung:The invention provides a multi-voltage independent output circuit for single-inductor transformation and a related product. The multi-voltage independent output circuit is provided with an input interface and a plurality of output interfaces, the output circuit outputs an access signal when detecting that any output interface is accessed to the electric equipment through the automatic power-on detection circuit; the current threshold detection circuit detects the current value of each output interface; the main control circuit outputs a corresponding enabling control signal when receiving the access signal, and outputs a corresponding enabling control signal according to the current value; the switch mode control circuit outputs a first enable signal when receiving the enable control signal; the LDO mode control circuit outputs a second enable signal when receiving the enable control signal; and each switch unit in the plurality of switch units is switched on under the control of the first enable signal or th
