Multi-voltage output voltage conversion circuit and method and storage medium thereof

The invention provides a multi-voltage output voltage conversion circuit and a multi-voltage output voltage conversion method so as to solve the problem of single output limitation of a traditional voltage conversion circuit. On the basis of a traditional voltage conversion circuit, a voltage division circuit is introduced, and the voltage division proportion is controlled and dynamically adjusted through a single-chip microcomputer, so that generation of different output voltages is achieved. Meanwhile, a software strategy is adopted, and the function of synchronously outputting a plurality of different voltages is realized on the basis of quickly switching different voltage division proportions. The DC-DC transformer has the advantages that through the synergistic effect of the voltage division circuit, the voltage output circuit and the single-chip microcomputer, the single DC-DC transformer can synchronously output a plurality of voltage values, and therefore the diversified requirements of modern circuit
