2.2 Board Setup
• Before applying power to the LM74701-Q1EVM, 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 LM74701-Q1EVM are verified, apply power to VIN. Figure 2-2 captures EVM board
setup.
