    摘要： In a switching power source which controls a current which flows in an inductor through a switching element which performs a switching operation in response to a PWM signal, and forms an output voltage by a capacitor which is provided in series in the inductor, a booster circuit which is constituted of a bootstrap capacity and a MOSFET is provided between an output node of the switching element and a predetermined voltage terminal. The boosted voltage is used as an operational voltage of a driving circuit of the switching element, another source/drain region and a substrate gate are connected with each other such that when the MOSFET is made to assume an OFF state, and a junction diode between one source/drain region and the substrate gate is inversely directed with respect to the boosted voltage which is formed by the bootstrap capacity.

    摘要： In a driver circuit constructing a switching power supply device that switches power transistors passing a current through a coil by a PWM mode, a current detection transistor, which is smaller in size than the low-potential side power transistor, and a current detection resistor are provided in parallel to the low-potential side power transistor. The same control voltage as the power transistor is applied to the control terminal of the current detection transistor. An operational amplifier is formed, that has the potential of the connection node between the current detection transistor and the current detection resistor applied to its inverse input terminal and a feedback loop, so as to make a pair of input terminals of the operational amplifier be at the same potential. A signal produced by the current detection resistor is thus outputted as a current detection signal.

    摘要： The present invention provides a digital signal recording apparatus and a recording medium for recording digital compressed picture information on magnetic tape, and specifically the structure of the recording apparatus that suitably records picture trick-play data separately from recording data for a normal replay and the recording medium on which data is suitably recorded.The digital signal recording apparatus includes picture data extraction circuit (103) for extracting picture data from the input digital compressed picture signal, trick-play-data generation means (105) for generating trick-play data while reducing the extracted picture data, and data disposition circuit (106) for disposing the trick-play data on tracks in position falling in line with the trace of the rotary magnetic head scanning in trick-play mode. The trick-play-data generation means (105) operates through program processing of a microprocessor (105). In addition, the recording apparatus generates trick-play data respectively applied to fast forward operation and rewind operation and record the data in predetermined locations on a medium, whereby faster display update on screen during the trick-play is achieved and rewind and replay operation can be performed suitably.
