Control manner of DC/DC converter and DC/DC converter

摘要

A DC/DC converter includes a first comparator configured to compare an output voltage to a reference voltage; a pulse generator circuit configured to generate a pulse signal when triggered by an output signal from the first comparator; a first switch circuit configured to open and close ON the basis of the pulse signal; an output voltage generator configured to generate the output voltage ON the basis of an input voltage supplied via the first switch circuit; a delay generator circuit configured to delay the output signal from the first comparator before outputting; and an error amplifier configured to control a delay time of the delay generator circuit ON the basis of a potential difference between the output voltage and the reference voltage.
