USB Type-C migration requires USB-PD sink control
Transitioning a device from a barrel jack to USB Type-C is not just a connector change. Devices must implement USB-PD sink functionality to operate correctly with the EPS. This includes negotiating appropriate voltage levels, such as 5V, 9V, 12V, 15V, or 20V, managing current delivery and ensuring protection against over-voltage, under-voltage and over-current conditions. As a result, USB-PD sink controllers become a critical building block in designs that adopt USB Type-C power input.
Diodes Incorporated has a comprehensive range of USB-PD controllers designed to support different performance, feature and cost targets. Whether the goal is a cost-effective USB Type-C migration, a high-performance USB-PD architecture, or a bi-directional USB Type-C power solution, Diodes offers a proven and scalable path forward. In addition, to help manufacturers prepare well ahead of the 2028 deadline, the company provides comprehensive reference designs with schematic examples and layout guidelines, rapid sampling and
end-to-end engineering and FAE support. Looking ahead
Regulation (EU) 2025/2052 does not directly require USB Type-C on devices. However, by mandating USB Type-C on EPS and enforcing
interoperability charging behavior, it reshapes the broader power ecosystem. Manufacturers that begin transitioning to USB Type-C with USB-PD now will reduce risk, improve user experience and stay ahead of regulatory and market expectations.
