Abstract
In a current resonance type DC/DC converter for converting an input voltage into an output voltage, a control circuit has an edge detection circuit for detecting edges of a driving control signal and a particular voltage to produce a logic control signal and a logic voltage signal, respectively, an error amount calculating arrangement for calculating an error amount on the basis of the logic control signal and the logic voltage signal, an off timing determining arrangement for determining an off timing of an energizing switch so as to make the error amount small, and a driving control signal generating arrangement for generating the driving control signal on the basis of the determined off timing.
