Board Setup
Before applying power to the LM74700EVM, 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.
Once all connections to the LM74700EVM are verified, apply power to VIN.
