Quick Start
2 Quick Start
1. Connect the voltage supply between the VIN and GND connectors or between VIN_EMI and GND of J5 to
include the on-board input filter in the input path. Use short and thick gauge wires to minimize inductance
and IR drop. Note that sense points for V
2. Connect the load of the converter between VOUT and GND connectors using short and thick wires.
3. Set the supply voltage at an appropriate level between 7 V to 36 V. The 7 V minimum ensures enough head
room for V
to equal 5 V at a 5-A load current. Set the current limit of the supply to an appropriate level to
OUT
supply needed current and protection.
4. Turn on the power supply. With the default configuration, the EVM powers up and provides V
5. Monitor the output voltage with sense points. The maximum load current must be 5 A with the LMR51450.
Note that the maximum output current need to derate if ambient temperature is high, especially if device is
operated at higher frequency, for example, 1 MHz.
