发明名称 POWER SUPPLY CIRCUIT
摘要 PROBLEM TO BE SOLVED: To provide a power supply circuit wherein power savings are achieved and multiple stable output voltages can be generated with a single transformer. SOLUTION: The secondary winding 22 of a transformer 10 is connected with a drive circuit 5 and a control circuit 6. In normal operation, the switching operation of the transformer 10 is controlled to adjust the value of first output voltage supplied to the drive circuit 5. In power saving mode, the switching operation of the transformer 10 is controlled to adjust the value of second output voltage supplied to the control circuit 6. The voltage line that connects the secondary winding 22, and the control circuit 6 is connected with a series regulator 8 only in normal operation mode. COPYRIGHT: (C)2006,JPO&NCIPI
