Abstract

See full text

Provided is a DC/DC converter capable of providing overvoltage protection reliably without being affected by, for example, an external element connected to an output terminal. The DC/DC converter includes a comparator, an RS-FF circuit, a drive circuit, and an ON-timer circuit, and the ON-timer circuit includes: a current source circuit which provides an electric current based on a power supply voltage; a ripple generation circuit which generates a ripple voltage; an averaging circuit which averages the ripple voltage; a timer circuit which generates an ON-timer signal; and an overvoltage protection circuit (clamp circuit).
