Title: Overvoltage protective circuit for switching power supply
Inventor: MANO YUTAKA
IPC: H02M3/28
Filed: 1994-05-31
Abstract: PURPOSE:To obtain an overvoltage protective circuit in which the overvoltage protective action voltage can be set precisely by providing means for regulating the anode potential of a Zener diode constituting the overvoltage protective circuit precisely. CONSTITUTION:An operational amplifier 19 has an input terminal connected with the voltage dividing point of a voltage divider circuit 14 and an output terminal connected with the joint of a Zener diode 16 and a resistor 17. The potential at the output terminal of the operational amplifier 19 is lower than the output voltage by a voltage value determined by the product of the resistance of a resistor R1 connected with the plus output terminal 7 and the magnitude of current flowing through the operational amplifier 19. Since the anode potential of the Zener diode 16 can be regulated by regulating the resistance of the resistor R1, fluctuation in the Zener voltage of the Zener diode 16 can be corrected. This constitution realizes an overvoltage protective circuit in which the overvoltage protective action voltage can be regulated precisely.

Filed: 1989-05-11
Abstract: PURPOSE:To control the output of the logic circuit while providing the fast speed performance of an ECL complementary input system by setting the level of a driving pulse of a prescribed transistor(TR) to have a prescribed relation with the level of a complementary signal. CONSTITUTION:When an input level of a TR T3 is an H level, a current flowing to an ECL flows to the TR T3 regardless of a signal supplied to TRs T1, T2, complementary signals A, inverse of A supplied to the ECL are fixed and no output is caused. On the other hand, with an input level of the TR T3 is an L level, the current of the TRs T1, T2 being components of the ECL depends on the complementary signals A, inverse of A and the entire circuit acts like the ECL. Thus, when a control signal is supplied to the TR T3, the output of the ECL is fixed. Furthermore, the amplitude of the input signal is small by the complementary signal supplied to the TRs T1, T2 and the output is controlled by the signal inputted to the TR T3 while the fast speed performance is being kept.
