摘要： A switching regulator includes a first switch, an inductor, a second switch, a controller to control a switching operation by switching the first switch and switching the second switch complementally to the first switch, and a reverse current detector to detect a reverse current that flows from an output terminal toward the second switch. The reverse current detector generates a proportional voltage that is proportional to a voltage at a junction node between the second switch and the inductor, and detects a generation or an indication of the reverse current based on the proportional voltage. The controller turns the second switch off to create a shutdown state when the reverse current detector detects the generation or the indication of the reverse current.

摘要： A charging current for a secondary battery is reduced when the secondary battery voltage gets close to a previously set constant voltage. When the charging current has become less than a charging completion current value as a reference for determining whether the charging has been completed, a charging control sequence circuit determines that the charging of the secondary battery has been completed and proceeds to a first flow consumption current mode. The charging control sequence circuit turns off a first switch to cut off an electrical connection to stop the operation of the charging control circuit, whereby a switching element and a switching element for synchronous rectification are turned off to cut-off electrical connections so that the charging current becomes 0 mA.
