1 STEVL-USBPDH USB Power Delivery (Type-C PD) W USB wall power adapter solution based on STCH0 and STUSB00 Data brief Features USB wall power adapter input: VC to VC USB voltage output: V, V and V Current limit: for all voltage level profiles Load power limited to W Cable compensation Isolated quasi-resonant flyback Efficiency 0% (approx.) USB Type-C Power Delivery compatible USB-IF certified 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 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 STCH0 Primary controller and STUSB00 USB PD controller. The V, V and V USB output voltage profiles all have a rating. The offline power supply is implemented in an isolated flyback topology based on the STCH0 quasi-resonant controller with ultra-low standby power consumption. The USB Power Delivery (PD) is managed by the STUSB00 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 dapter applications.
