2.2 Board Setup
Before applying power to the LM74700DDFEVM, verify all external connections. Turn off external power supplies
and connect them with the proper polarity to the VIN and GND1 connectors. An electronic or resistive load must
be connected at the output VOUT and GND2 connectors. The tests outlined in this document are conducted with
3-A constant current as the load and 12 V at the input. Make sure that the external power-supply source for the
input voltage is capable of providing enough current to the output load so that the output voltage can be
obtained.
When all connections to the LM74700DDFEVM are verified, apply power to VIN. Figure 2-2 captures EVM board
setup.
