STMICROELECTRONICS EARNS USB-IF CERTIFICATION FOR COMPLETE USB PD EPR SOLUTION

STMicroelectronics has achieved USB-IF (USB Implementers Forum) certification of two ICs for use in adapter (source) and device (sink) sides of a USB Power Delivery (USB PD) EPR power supply/charger product. The new ICs extend the range of a universal charger to 140W. Now, a single AC to DC adapter can charge equipment such as computers, smart-home actuators, power tools, and e-bikes, as well as traditional applications including smartphones, tablets, and smartwatches.

Certified by the USB-IF to deliver up to 140W (28V@5A), the REF_STUSB140W (sink) and the ST-ONEHP (source) represent two halves of the complete USB PD reference design for the solution. The sink reference design assures designers of an efficient, cost-effective working solution for seamless USB PD integration. The ST-ONEHP is supplied pre-loaded with certified USB PD 3.1 EPR firmware.

Together, the new USB solutions enable a larger universe of applications to adopt a USB-C connector and hence allow charging from a universal AC to DC adapter. This reduces the number of adapters the end user needs to carry and cuts e-waste, while also lowering transportation costs and CO2 emissions.

An active contributor to the USB PD 3.1 specification which includes the Extended Power Range (EPR) definition, the ST solutions are among the first designs certified.
