摘要： A power-supply control IC is included in a switching power supply which drives to turn on and off a semiconductor switching device connected to a DC power supply in series to supply a predetermined constant voltage to an external load, and is a semiconductor device including a semiconductor circuit which controls on and off of the semiconductor switching device. When a current flowing through the load is abruptly increased to cause an error voltage to exceed a predetermined first threshold voltage after the end of a PWM on-pulse generated in synchronization with a switching cycle, a second PWM on-pulse is generated within the same switching cycle. Furthermore, in a plurality of switching cycles after the switching cycle in which the second PWM on-pulse is generated, the first threshold voltage for comparison with the error voltage is switched to a second threshold voltage higher than the first threshold voltage.

摘要： A semiconductor device for control applied to a constant-voltage power supply device includes a digital-analog converter circuit which outputs a reference voltage corresponding to a value of a first register with taking an output voltage of a reference voltage source as a criterial reference voltage, and generates a control signal for driving a power semiconductor device based on an output voltage of an error amplifier which differentially amplifies a feedback voltage obtained by resistive-dividing on an output voltage of the constant-voltage power supply device and the reference voltage. An analog-digital converter circuit which converts the feedback voltage to a digital value with taking the output voltage of the constant-voltage power supply device as a reference voltage is provided, and based on the output, a value of a first register is corrected so as to offset an effect of an error in voltage dividing ratio of a voltage dividing resistor circuit.

In a switching power source device, one of source/drain routes is connected to an input terminal to which an input voltage is supplied, a predetermined voltage to be restricted is supplied to a gate, and using a MOSFET which provides a current source between another source/drain route and a ground potential of the circuit, a clamp output voltage which corresponds to the input voltage is obtained from another source/drain route. The switching power source device further includes a first switching element which controls a current which is made to flow in an inductor such that the output voltage assumes a predetermined voltage and a second switching element which clamps an reverse electromotive voltage generated in the inductor when the first switching element is turned off to a predetermined potential. In such a switching power source device, the voltage clamping circuit is used in a feedback route for setting a dead time.
