Publication number: 20240146205Abstract: A flyback power converter includes a power transformer, a first lossless voltage conversion circuit, a first low-dropout linear regulator and a secondary side power supply circuit. The first low-dropout linear regulator (LDO) generates a first operation voltage as power supply for being supplied to a sub-operation circuit. The secondary side power supply circuit includes a second lossless voltage conversion circuit and a second LDO. The second LDO generates a second operation voltage. The first operation voltage and the second operation voltage are shunted to a common node. When a first lossless conversion voltage is greater than a first threshold voltage, the second LDO is enabled to generate the second operation voltage to replace the first operation voltage as power supply supplied to the sub-operation circuit; wherein the second lossless conversion voltage is lower than the first lossless switching voltage.Type: ApplicationFiled: September 23, 2023Publication date: May 2, 2024Inventors: Shin-Li Lin, He-Yi Shu, Shih-Jen Yang, Ta-Yung Yang, Yi-Min Shiu, Chih-Ching Lee, Yu-Chieh Hsieh, Chao-Chi Chen
