2.1 Quick Start

  1. Connect the voltage supply between the VIN_EMI and GND_EMI supply connections.
  2. Connect the load between the VOUT and GND test points.
  3. Set the supply voltage at an appropriate level between 3.5 V to 36 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 VOUT = 3.3 V.
  5. Monitor the output voltage. The maximum load current is rated at 2 A with the LMR43620-Q1 device.
