| Zusammenfassung: | The present invention relates to a technique for a semiconductor device. More particularly, the present invention relates to a technique effectively applicable to a semiconductor device having a power supply circuit.
Disclosed is a technique capable of improving a power supply efficiency in a power supply circuit. A power MOSFET in a high side of a combined power MOSFET constituting a DC-DC converter is constituted of a horizontal MOSFET, and a power MOSFET in a low side thereof is constituted of a vertical MOSFET. |
