摘要:
In order to reduce parasitic inductance of a main circuit in a power supply circuit, a non-insulated DC-DC converter is provided having a circuit in which a power MOS•FET for a high-side switch and a power MOS•FET for a low-side switch are connected in series. In the non-insulated DC-DC converter, the power MOS•FET for the high-side switch is formed by a p channel vertical MOS•FET, and the power MOS•FET for the low-side switch is formed by an n channel vertical MOS•FET. Thus, a semiconductor chip formed with the power MOS•FET for the high-side switch and a semiconductor chip formed with the power MOS•FET for the low-side switch are mounted over the same die pad and electrically connected to each other through the die pad.
