Zusammenfassung:	There is disclosed a dc-to-dc converter provided with dual-mode current and voltage regulation and a "soft" start characteristic in which a digital-type feedback control is obtained based upon the relative priority of the arrival of the respective feedback pulses at the driving circuit for the converter transistors. In addition, a shut-down circuit checks both of two redundant feedback circuits for the absence of feedback pulses for a prescribed time before triggering shutdown. Either of the two redundant feedback circuits is individually capable of regulating the output voltage or the output current if the output load is balanced. With a high impedance unbalanced load, the voltage regulator on the output lead that tends to experience high voltage takes control and limits the maximum output voltage.
