Title: Method of controlling output voltage of switching regulator
Inventor: YOSHIHARA TAKAO
IPC: H02H9/04
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To stabilize the output voltage by providing a separate error amplifier from an error amplifier operating normally, and setting the output voltage set value not less than the output voltage set value of the error amplifying circuit and besides not more than the tolerable maximum overcurrent voltage. SOLUTION: The primary current of a transformer 2 is detected at both ends of a resistor 4 for current detection, and it is inputted into a C/A terminal. The pulse width is controlled so that the output voltage may be constant, by widening the width of the switching pulse outputted from an OUT terminal when the output voltage is low, and narrowing the pulse width when the output voltage is high. If an error amplifier 6 goes wrong, and the pulse width widens to maximum, the output voltage goes up and becomes overvoltage. Then, when the output voltage reaches the output voltage set value of the error amplifier 7, the error amplifier 7 operates to control the output voltage.  The output voltage set value of the error amplifier 7 is set between the output voltage ripple width of the error amplifier 6 and the tolerable maximum overvoltage so as to control the output voltage, thus the protection of load is performed.
