3.1 HARDWARE DESCRIPTION
3.1.1 Power Source
The EVB-UTC2000-DFP can be powered in one of two ways:
1.
Host/Hub Port VBUS: The board can be powered by 5V VBUS sourced from
the connected host port. Do not operate with SW1 in the 1.5A or 3.0A modes and
attempt to draw 1.5A or 3.0A when connected in this way, as Legacy USB Type-A
host ports typically cannot support this amount of current draw.
2. External 5V Supply: An external 5V supply may be connected to TP1 to test
1.5A and 3.0A charging. Be sure to remove the R3 zero-ohm resistor to prevent
voltage back drive to the host/hub port, as shown in
Figure 3-3 .
