摘要： A switching power supply device includes a voltage conversion transformer, a primary-side control semiconductor device, a rectification and smoothing circuit, an output voltage detection circuit, a failure detection circuit, and a switch. The primary-side control semiconductor device generates a driving signal which controls a switching element connected to a primary winding of the transformer. The rectification and smoothing circuit is connected to a secondary winding of the transformer. The output voltage detection circuit detects a secondary-side output voltage of the transformer and transmits a feedback signal corresponding to the output voltage to the primary-side control semiconductor device through an insulated signal transmitter. The failure detection circuit detects a failure on a secondary side of the transformer. The switch cuts off a current flowing to the insulated signal transmitter if the failure detection circuit detects a failure.

摘要： A semiconductor device for a switching power supply includes first and second external terminals, ON and OFF timing generation circuits, and a drive pulse generation circuit. To the first and second external terminals, a feedback voltage and a voltage induced in an auxiliary winding are input, respectively. The ON and OFF timing generation circuits respectively generate timing signals turning on and off a switching element based on the voltages. The drive pulse generation circuit generates a pulse signal based on these signals. The ON timing generation circuit includes: a bottom detection circuit detecting a lowest point of the voltage of the second external terminal; and a timer circuit, and operates in a PWM mode and a quasi-resonant mode in response to a timing of an output of the timer circuit being before a timing of an output of the bottom detection circuit and the reverse case, respectively.
