In an effort to reduce e-waste, USB-IF redefined the role of a USB port as a universal interface for power too. Focus was given for faster and efficient power transfer to meet the growing needs of battery-powered applications. This approach was widely accepted in the USB world and is also gaining popularity among the non-USB OEMs as a preferred method of power delivery, such as electric shavers, portable speakers. Unlike Type-A ports on the wall socket, a Type-C PD port with higher power can serve a wider spectrum of consumer electronics and really help to reduce adapter clutter.

The intrinsic design challenges (restricted PCB area and thermal dissipation inside the gang-box) in a wall socket design make the Type-C PD integration more challenging. That being said, let’s see how TI’s highly integrated and configurable TPS665988DH PD controller can be of help to roll out your next Type-C PD wall socket, with a short development cycle to keep up market pace.
