4.8 USB-C Connector
USB-C connector supports multiple use case scenarios and provides the following functions:
Provide board power supply in both DFP and DRP mode
Source power to external peripherals when board is powered through VIN
expose High Speed (480Mbps) or Full Speed (12 Mbps) USB Host/Device interface
expose DisplayPort output interface (optional)
The DisplayPort interface is usable in conjunction with USB and can be either used with a simple cable adapter
when board is powered via VIN or with dongles able to provide power to the board while simultaneously
outputting DisplayPort and USB. Such dongles usually provide an ethernet over USB port, a 2 port USB hub and a
USB-C port that can be used to provide power to the system.
4.9 Power Tree
All power conversion on the Portenta H7 is handled by the PF1550 PMIC. Current is drawn by VUSB, VIN or VBATT
automatically according to rules specified by the PMIC. The VCC is driven by a buck converter configured to provide
3V3 that is accessible on both the MKR headers and the HDR connector. Two other buck converters provide 3V1
and 2V8 outputs. Additionally, three precision LDO provide low-ripple outputs of 1V0, 1V2 and 1V8. Voltage range
and max current are provided as a general guideline only. Consult the PF1550 datasheet for specific details.
