Description
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.
