Abstract
There is provided a DC-DC converter which is safe and secure, but yet with low power consumption. The DC-DC converter is configured to monitor the output voltage of an error amplifier, and detect that the output voltage of the error amplifier becomes a fixed value or smaller to drive an overheat protection circuit and a supply voltage monitoring circuit intermittently.
