Abstract
A flyback boost circuit includes an output voltage detection terminal provided to a secondary winding of a transformer of the flyback boost circuit, and configured to detect an output voltage. Prior to the start of a boost operation, current is supplied to a secondary side of the transformer via the output voltage detection terminal to detect a voltage generated at the output voltage detection terminal, to thereby detect an unwired state by determining whether or not there is floating of the output voltage detection terminal or a grounding terminal of the secondary winding of the transformer.
