摘要： A power supply topology is used in which a transistor is provided on the side of an output node of a rectifying circuit. An inductor is provided on the side of a reference node, a resistor is inserted between the transistor and the inductor, and one end of the resistor is coupled to a ground power supply voltage of a PFC circuit. The PFC circuit includes a square circuit which squares a result of multiplication of an input voltage detection signal and feedback information (output voltage of an error amplifier circuit). The PFC circuit drives on the transistor when a detection voltage developed at the resistor reaches zero, and drives off the transistor when the detection signal reaches an output signal of the square circuit.

摘要： There is provided a switching power supply device of hysteresis current mode control system which assures excellent response characteristic for change of output current and reduction of power consumption. In a switching regulator of hysteresis current mode control system, a sense resistor connected in series to a coil is eliminated, a serially connected resistor and a capacitor are connected in parallel to a coil in place of such sense resistor. Thereby, a potential of a connection node of these resistor and capacitor is inputted to a comparator circuit having the hysteresis characteristic for comparison with the reference voltage. Accordingly, a switch may be controlled for ON and OFF states.

摘要： A PFC counter which controls a switching element of voltage step-up chopper circuits arranged in parallel has a circuit (SLOG) generating a switch signal (GD_S) whose phase is shifted from that of a switch signal of one of the switching elements. This circuit has a first counter (COUNTM) which counts clock signals by a cycle unit of one of the switch signals; a second counter (COUNTS) which counts clock signals by a cycle unit having a predetermined phase difference with respect to one of the switch signals; and a first register (REG1) which holds a value counted by the first counter corresponding to a high-level period of one of the switch signals.
