Patent number: 11740672Abstract: A multiport USB-PD adaptor including a flyback-converter, a USB controller including a USB-PD subsystem and buck-controller, and multiple buck and bypass-circuits, and methods for operating the same are provided. Generally, the adaptor is operated in a buck-bypass-mode, in which at least one buck-circuit is bypassed and the flyback-converter is operated to generate an input voltage (VIN) to the buck-circuits equal to a requested output voltage (VOUT_C), which is then coupled directly to the associated port. Buck-circuits coupled to other active ports can also be bypassed if the requested VOUT_Cs are the same, or the buck-circuits operated to provide another VOUT_C. If a bypass-circuit unavailable, the adaptor is operated in a variable-buck-input-mode by determining a highest VOUT_C requested on any port and setting VIN to a sum of the highest VOUT_C and an offset voltage. Buck-circuits coupled to active ports are then operated to provide the requested output voltages.Type: GrantFiled: July 28, 2021Date of Patent: August 29, 2023Assignee: Cypress Semiconductor CorporationInventors: Chuan-yu Lin, Jen-Hui Cheng, Hua-ping Cao, Yong-shuang Zhu, Hsiang-Nien Kuo
