DC-DC CONVERTER CIRCUIT

A DC-DC converter circuit includes a DC-DC converter IC that inputs, via an input terminal connected to a power supply input line, a direct-current voltage converted from an alternating-current voltage and supplied by the power supply input line. The DC-DC converter IC outputs a direct-current volta...

Zusammenfassung:A DC-DC converter circuit includes a DC-DC converter IC that inputs, via an input terminal connected to a power supply input line, a direct-current voltage converted from an alternating-current voltage and supplied by the power supply input line. The DC-DC converter IC outputs a direct-current voltage having a value converted by operation of the DC-DC converter IC. The DC-DC converter IC is able to operate when a voltage of a specified threshold value or greater is input from an enable terminal. The DC-DC converter circuit also includes an enable control circuit that makes the voltage input to the enable terminal equal to the threshold voltage or greater when the direct-current voltage supplied from the power supply input line reaches a specified value.
