This is HOW you do it

Implementation can be as simple as the bellow picture, which uses a standalone SINK PD controller, such as STUSB4500 and a PMOS. Get the source files for a minimal implementation here: STREF-SCS001V1 or order an evaluation board here: STEVAL-ISC005V1

STUSB4500 is stand-alone, tiny, safe, certified, and easily customizable. STUSB4500 Certification ID: 1000133

This is WHY you should do it

For devices up to 100W (20V; 5A), the USB Power Delivery standard now offers a charging connector alternative to any input power plug (USB micro-B or DC barrel for instance). Main benefits are the following:

1)      SMARTER DESIGN: Thanks to its thickness and robustness, the type-C connector makes the product shape smarter than with a legacy DC barrel.

2)      UNIVERSALITY: Additionally, in most cases, it makes the device compliant with universal AC adapters.

3)      COST SAVING: For vendors, no need any longer to include in the box a dedicated AC adapter for every device.

4)      MORE CONVENIENT: For users, no need to carry multiple AC adapters when traveling. A cable works for all.

5)      ECO-FRIENDLY: For the planet, less electronic wastes.
