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

Publication number: 20240136346Abstract: A semiconductor die package includes an inductor-capacitor (LC) semiconductor die that is directly bonded with a logic semiconductor die. The LC semiconductor die includes inductors and capacitors that are integrated into a single die. The inductors and capacitors of the LC semiconductor die may be electrically connected with transistors and other logic components on the logic semiconductor die to form a voltage regulator circuit of the semiconductor die package. The integration of passive components (e.g., the inductors and capacitors) of the voltage regulator circuit into a single semiconductor die reduces signal propagation distances in the voltage regulator circuit, which may increase the operating efficiency of the voltage regulator circuit, may reduce the formfactor for the semiconductor die package, may reduce parasitic capacitance and/or may reduce parasitic inductance in the voltage regulator circuit (thereby improving the performance of the voltage regulator circuit), among other examples.Type: ApplicationFiled: April 17, 2023Publication date: April 25, 2024Inventors: Chien Hung LIU, Yu-Sheng CHEN, Yi Ching ONG, Hsien Jung CHEN, Kuen-Yi CHEN, Kuo-Ching HUANG, Harry-HakLay CHUANG, Wei-Cheng WU, Yu-Jen WANG

Patent number: 11436507Abstract: Nodes of a weighted tree each have their own weight. A normalized weight of a node, relative to other nodes in the tree, is determined based on a proportional weight of the node and a lesser unique sum of the node, as well as those of the node's parents and grandparents, up to a root of the tree. The proportional weight and lesser unique sum of a given node depend only on the unique weights of the sibling group including the given node. Thus, if a weight is modified, the normalized weight can be updated without necessarily recalculating the entire tree.Type: GrantFiled: November 21, 2019Date of Patent: September 6, 2022Assignee: International Business Machines CorporationInventors: Yu-Ching Chen, Tuo Wang, Ziyue Jason Wang, Lior Aronovich
