Abstract
Upon detecting an external signal which instructs to stop discharge, an input voltage equal to or less than a set value for the prevention of overdischarge, or an output voltage equal to or more than a set value for the prevention of output of an overvoltage, a control unit (12) stops discharge to a load (40) by opening a switching element (4b) of a step-down unit (11b). Upon detecting that an external signal is reset or an input voltage equal to or more than a set value larger than the set value for the prevention of overdischarge, the control unit (12) resumes discharge to the load (40) by setting the switching element (4b) in a switching operation state or short-circuiting it.
