Title: Switching power supply unit
Inventor: SHIMIZU YOSHIFUMI
IPC: H02M3/28
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To inhibit generation of overcurrent by a circuit having a simple configuration when an output voltage is dropped. SOLUTION: When the output voltage in output terminals 11 and 12 is dropped to a specific threshold, an output level detection section 17 of a variable circuit 71 turns on a transistor 18, thus changing the capacitance constituent of a time constant circuit 101 A and oscillation conditions in an IC 13A for control, reducing the frequency of a control pulse signal generated in the IC 13A for control, lengthening the pulse interval in the control pulse signal, hence shortening the period while an MOSFET 5 controlled by the control pulse signal is on, and hence inhibiting increase in the output current.
