    摘要： A DC-DC converter includes a regeneration preventing circuit to bring a synchronous rectifying switching element to an OFF-state when an output of an error amplifier is lower than a lower-limit potential of a triangular-wave signal, that is, when the output of the error amplifier deviates from a voltage range of the triangular-wave signal in a side (direction), which would cause a smaller ON duty ratio of a main switching element. This configuration prevents a rise of voltage in an input side due to a regenerative operation at startup when a pre-bias voltage exists. Also, the configuration prevents fluctuations of an output voltage at a sudden change of a load current and a drop of the output voltage at transition from a soft start state to a normal operation state when the load current is small.

    摘要： The invention is directed to enhancement of performance of a back surface incident type semiconductor device having a light receiving element and a manufacturing method thereof without increasing a manufacturing cost. A supporting body is attached to a front surface of a semiconductor substrate formed with a light receiving element and its pad electrode. Then, the supporting body is etched to form a via hole penetrating the supporting body and exposing the pad electrode. Then, a wiring connected to the pad electrode and extending onto a front surface of the supporting body through the via hole is formed. Lastly, the semiconductor substrate is separated into a plurality of semiconductor dies by dicing. The semiconductor device is mounted so that the supporting body faces a circuit board.

    摘要： A piezoelectric transformer inverter includes an inverter unit and a step-down chopper unit. The inverter unit includes a ceramic piezoelectric transformer whose secondary terminal is to be connected to a fluorescent tube, a drive unit which is connected to a primary terminal of the ceramic piezoelectric transformer, and an inverter control circuit for controlling luminance of the fluorescent tube to a desired value. The step-down chopper unit includes a switching device which is disposed on the side where the voltage of the inverter unit is input, a free wheeling device connected between the switching device and a reference potential, and a PWM feedback control circuit for providing a feedback control to maintain an average voltage of the rectangular-wave voltage of the switching device constant. In the piezoelectric transformer inverter, even when the feedback control by the PWM feedback control circuit is impossible, the on-duty of the chopper unit is restricted so that it is not greater than a given amount.
