Integrated Design of a Controller and Compliant Power Supply for USB Power Delivery

This paper presents a design of an integrated controller and compliant power supply for USB Power Delivery (USB-PD). The design objectives focus on efficiency, cost-effectiveness, and reliability, while adhering to the requirements of USB-PD. The design process employs an OA (OpenAccess) based flow in Cadence Virtuoso, which significantly enhances the integration and interoperability of the design within the Cadence environment. The design is validated up to 100W of delivered power By leveraging the integrated controller, designers can create USB power supplies that are not only efficient and safe, but also capable of meeting the growing power demands of modern devices. This work will provide valuable insights into the feasibility and potential benefits of this integrated approach. The findings of the present work will contribute to the ongoing discourse in this field and may pave the way for more efficient and compact USB PD solutions in the future.
