2.1.2 Test Equipment

  • Power Supply: Use an input voltage source capable of supplying 0V to 72V and 10A.
  • Voltmeter 1: Measure the input voltage at VIN+ to VIN–.
  • Voltmeter 2: Measure the output voltage at VOUT+ to VOUT-.
  • Ammeter 1: Measure the input current. Connect to the power supply and VIN+.
  • Load 1: The load must be an electronic load capable of constant-voltage (CV) regulation. The electronic load must be capable of sinking 10A at 12V and below.

Oscilloscope: With the scope set to 20MHz bandwidth and AC coupling, measure the output voltage ripple directly across an output capacitor with a short ground lead normally provided with the scope probe. TI does not recommend using a long-leaded ground connection because this can induce additional noise given a large ground loop. To measure other waveforms, adjust the oscilloscope as needed. Always use caution when touching any circuits that can be live or energized.
