Operation

2.1

Quick Start

1. Connect the voltage supply between the VIN_EMI and GND test points.

2. Connect the load between the VOUT and GND test points.

3. Set the supply voltage at an appropriate level between 5.5 V to 65 V. Set the current limit of the supply

to an appropriate level.

4. Turn on the power supply. With the default configuration, the EVM powers up and provides V

OUT

= 3.3

5. Monitor the output voltage. The maximum load current must be 0.6 A with the LMR36506 device.
