This board has been physically tested and validated; it is not for sale.
This USB Power Delivery wall adapter is a USB-IF certified solution with a 45 W isolated power supply with USB Power Delivery controller.
This USB Type-C PD wall power adapter design is for universal line voltage applications based on the STCH02 Primary controller and STUSB4700 USB PD controller.
The 5 V, 9 V and 15 V USB output voltage profiles all have a 3 A rating.
The offline power supply is implemented in an isolated flyback topology based on the STCH02 quasi-resonant controller with ultra-low standby power consumption. The USB Power Delivery (PD) is managed by the STUSB4700 and is Type-C compatible: power negotiation, Vbus discharge, protections, etc. are entirely managed by the IC.
The USB power supply architecture connects a power board with a controller board. This design optimizes the form factor and lets you scale the power section up or down to suit different USB Power Adapter applications.
