4.1.1 Test Setup

Figure 4-1 shows the required test setup to evaluate the EVM.

LM5126AEVM-BST EVM Test SetupFigure 4-1 EVM Test Setup

The following test equipment is needed:

  • Power supply: The power supply needs to support 20V/80A.

  • Electronic load: The electronic load needs to sink 500W at 60V.
  • Multimeters (optional)
    • Voltmeter 1 (VIN): Capable of measuring input voltage of 20V
    • Voltmeter 2 (VOUT): Capable of measuring output voltage of 60V
    • Ammeter 1 (IIN): Capable of 80A DC measurement.
    • Ammeter 2 (IOUT): Capable of 25A DC measurement
  • Oscilloscope: Minimum 200MHz bandwidth
