Power diagram
The following diagram describes the power architecture and the maximum voltage and current limits, under which
functions can be safely used on the B-G474E-DPOW1 product. In any case, ensure the total power budget of the
application always conforms to the selected 5V power source mode, if not malfunction can occur. For detailed
configuration, refer to the relevant function description and technical application notes.
Note:
When using 5V_VOUT and 3V3_OUT to power external functions on 32-pin extension connectors, it can
be necessary to use one of the two following power sources, depending on the application power
budget:
•
