ST USB power supply overall solution obtains USB-IF certification: output power reaches 140w, supports charging of multiple devices

Matteo Lo Presti, executive vice president, Analog, MEMS and Sensor Products Group, STMicroelectronics, said: “ST is a pioneer in the semiconductor industry and can now provide USB-IF certified reference designs and chips to meet customers’ requirements for high-power, industry-leading Demand for standard universal chargers/adapters. By responding quickly, supporting USB Powered EPR, and obtaining product certification, we are accelerating the replacement of custom power plugs and DC adapters in many applications with USB-C® connectors using universal AC or DC Adapter charging reduces cost and environmental impact. "

Passed USB-IF certification, with output power up to 140W (28V@5A), REF_STUSB140W (power receiving chip) and ST-ONEHP (power supply chip) are the two halves of the overall USB PD reference design. The powered reference design ensures designers have an energy-efficient and cost-effective prototyping solution for seamless USB PD integration. The ST-ONEHP chip comes pre-installed with certified USB PD 3.1 EPR firmware.

Taken together, the new USB solution helps drive wider adoption of USB-C connectors for charging with universal AC-DC adapters, which will reduce the number of adapters and e-waste end users carry with them, while also reducing shipping costs and CO2 emissions.

Jeff Ravencraft, President and Chief Operating Officer of USB-IF, said: "The USB PD 3.1 specification represents a major technological breakthrough that can meet the charging needs of more devices above 100W. As the first USB PD EPR reference design to obtain USB-IF certification, ST’s latest IC will accelerate the transition from proprietary power connectors to USB Type-C®.”

As an active participant in the USB PD 3.1 specification and the definition of the extended power range (EPR), STMicroelectronics is one of the first semiconductor manufacturers to obtain certification.
