Low-Cost USB-C & USB PD 100W/140W Power Supply with Multiple Outputs

USB-C and USB Power Delivery (PD) became the standard for power supply of mobile devices. These designs implement low-cost single and dual port USB-C and USB PD 3.1 power adapters with 5-20V/5A 100W dual outputs or a 5-28V/5A 140W single output. The designs feature BOMs optimized for cost and power efficiency to minimize the size and price of the adapter.
