Abstract

Official abstract text for this publication.

Disclosed is a semiconductor device that includes an N-channel MOS transistor and a control voltage generation circuit. The N-channel MOS transistor controls the supply of a power supply voltage obtained by stepping down a DC voltage. The control voltage generation circuit clips the gate voltage of the N-channel MOS transistor at a control voltage not higher than a predetermined voltage in accordance with the DC voltage.

First claim

Opening claim text (preview).

What is claimed is: 1 . A semiconductor device comprising: an input power supply terminal configured to receive a first voltage; a step-down circuit configured to generate a second voltage based on the first voltage, the step-down circuit being coupled with the input power supply terminal and having an output node configured to supply the second voltage; an output power supply terminal configured to be coupled to a load circuit; an N-channel MOSFET whose drain, source and ga…
