ABSTRACT:
A differential output DC-DC converter capable of decreasing power consumption is presented. The differential output DC-DC converter1comprises output terminals VP and VM connected to both ends of load, and a switching regulator10for passing a source current. It further comprises a third transistor FET3, a choke coil L2, and a fourth transistor FET4for rectifying a sink current in a flowing direction, and further a second regulator for allowing the sink current to flow, and issuing a voltage higher than a grounding point GND voltage and lower than a voltage of an output terminal VP, to an output terminal VM.
