ABSTRACT:
The present invention enhances voltage conversion efficiency of a semiconductor device. In a non-isolated DC-DC converter that includes a high-side switch power MOSFET and a low-side switch power MOSFET, which are series-connected, the high-side switch power MOSFET and driver circuits for driving the high-side and low-side switch power MOSFETs are formed within one semiconductor chip, whereas the low-side switch power MOSFET is formed in another semiconductor chip. The two semiconductor chips are sealed in a single package.
