2.2 Power Supply Selection

Power options for the DP83TD555EVM include:

1. Single 5V Power Supply coming from MikroBUS connector

The DP83TD555EVM power is supplied by the 5V input connection in the image below. Single supply operation uses on-board LDOs to generate the voltages required for operating various sections of the EVM.

Before supplying power at the 5V input, make sure the correct shunts are added to the appropriate headers to properly operate the on-board LDOs as seen in the figure below.

2. Optional External VBAT: Without the J5 shunt, 5V Power Supply coming from MikroBUS connector powers up VDDA/VDDIO. External Power supply can be used on the left pin of J5 for VBAT, up to 48V.
