A digital-to-analog converting circuit for power soft-switching, comprising: a metal-oxide-semiconductor field-effect transistor (MOSFET); a digital-to-analog control circuit, for controlling the MOSFET to operate in either the cut-off region, the saturation region or the linear region; a digital control unit, using an output signal so as to control an input current into the MOSFET; and a DC-to-DC inverter, controlled by the MOSFET so as to invert external DC power into a certain level for electronic products.
