摘要： In a conventional power circuit device, such as a power MOSFET monolithic integrated circuit device and a compound device, since five lead pins are lead out from the packaging with even intervals, sufficient separation distances between the third pin of a high voltage and other adjacent pins cannot be secured. According to this invention, the distances between the third pin and other adjacent pins are expanded so as to become wider than the distances between other pins. Furthermore, the third pin is formed into an upper position, its adjacent pins are formed into a lower position, and other pins are formed into a middle position. Thereby, sufficient separation distances between the third pin of the high voltage and other adjacent pins can be secured. Therefore, a structure favorable in terms of safety can be provided. Furthermore, by providing a full-mold packaging, the header portion is not exposed to assure an easy handling.

摘要： In a DC-DC converter of this invention, a voltage detection circuit is connected in parallel with an output switching device, and the voltage detection circuit is put into operation a predetermined time after the output switching device is turned on. In addition, a detection switching device, which constitutes the voltage detection circuit, is designed to have a higher ON resistance than an ON resistance of the output switching device.

摘要： A detection resistor is disposed in a main current path in order to detect an output current flowing through an output switching device in a conventional DC-DC converter that converts a DC input voltage into a stepped down DC output voltage by turning on/off of the output switching device. At that time, the detection resistor generates heat that is not negligible. In a DC-DC converter of this invention, a voltage detection circuit is connected in parallel with an output switching device, and the voltage detection circuit is put into operation a predetermined time after the output switching device is turned on. In addition, a detection switching device, which constitutes the voltage detection circuit, is designed to have a higher ON resistance than an ON resistance of the output switching device.
