Title:
DC-DC converter
Document Type and Number:
Japanese Patent JP6289647
Kind Code:
B2
Abstract:
An object is to provide a technique enabling conversion efficiency to be increased irrespective of an operating ambient temperature. A DC-DC converter includes switching elements, a drive unit which drives the switching elements to conduct synchronous rectification, a freewheel diode connected in parallel to the switching element, and a temperature detection circuit which detects a temperature of the freewheel diode. The drive unit stops driving the switching element when the temperature detected by the temperature detection circuit is equal to or lower than a predetermined first threshold value.
