Title:
スイッチング電源装置
Document Type and Number:
Japanese Patent JP4212350
Kind Code:
B2
Abstract:
To provide a novel switching power supply in which a waiting signal for turning a switching element on/off is eliminated.
A switching power supply circuit comprises a main switching element Q1 and a series capacitor C4 in an input line. The switching power supply circuit is connected with a pulse oscillation circuit IC1 outputting a pulse signal. The pulse oscillation circuit IC1 and the output terminal of the main switching element Q1 are connected with the input part of an internal detection circuit 12. The internal detection circuit 12 detects the pulse signal supplied from the pulse oscillation circuit IC1 and controls the switching timing of the main switching element Q1.
