摘要:
In a switching power source apparatus which outputs a DC output voltage converted from a DC power source voltage, the DC output, voltage is compared with a reference voltage to generate a feedback signal which decreases as the DC output voltage increases. A current detecting signal which decreases as the output current increase is also generated. The smaller of the feedback signal and the current detecting signal, as a comparison signal, is compared with a triangular signal in a PWM comparator to produce a PWM signal. A semiconductor switch is on-off controlled by the PWM signal. Therefore, the apparatus can perform a constant voltage control with a current limit function.
