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.
