    Abstract: A switching power supply device performs a stable operation with fast response for a semiconductor integrated circuit device. A capacitor is provided between the output side of an inductor and a ground potential. A first power MOSFET supplies an electric current from an input voltage to the input side of the inductor. A second power MOSFET turned on when the first power MOSFET is off allows the input side of the inductor to be of a predetermined potential. A first feedback signal corresponding to an output voltage obtained from the output side of the inductor and a second feedback signal corresponding to an electric current flowed to the first power MOSFET are used to form a PWM signal. The first power MOSFET has plural cells of a vertical type MOS-construction.

    Abstract: A switch mode voltage regulator with synchronous rectification that produces ripple cancellation with fast load response is described. The switch mode voltage regulator comprises a main step-down regulator with synchronous rectification with an auxiliary step-down regulator that produces an output ripple cancellation current that is equal but opposite to the output ripple of the main regulator during static load conditions. During changing load conditions a feedback control circuit changes the duty cycle of the main regulator while a time-delay circuit prevents a change of the duty cycle in the auxiliary regulator. Thus, the main regulator is allowed to change its average current while preventing a counteracting average current change in the auxiliary regulator. An embodiment is described in which the duty cycle in the auxiliary regulator is changed in phase with the duty cycle of main regulator to further improve the dynamic response to load changes. A sub-cycle circuit is also described that overrides the feedback control circuit to improve the dynamic response to load changes. Accordingly, a fast transient response can be achieved with a switch mode regulator that has a low ripple voltage.

    Abstract: A built-in drive-power-source semiconductor device of low cost having a good switching characteristic and a decreased switching loss. In operation, a reference charge potential is applied to a charging IGBT by a first constant voltage diode thereby turning on the IGBT to charge a battery means. When the charge potential of the battery means reaches a prescribed level, a MOSFET is turned on by a second constant voltage diode, shortcircuiting the first constant voltage diode, causing the charging IGBT is turn off to eliminate overcharging of the batter means and maintain the potential of the battery means at a prescribed value. The semiconductor device includes a light emitting circuit for emitting light in response to an input control signal, a photo voltage generating circuit for charging the battery portion with at least a portion of the photo voltage generated in response to light from the light emitting circuit and, a disabling circuit for disabling the output IGBT when the battery means has not yet reached a sufficient level of charge potential.
