4.2 Test Equipment

Power Supply: Connect to VIN(-) and Ammeter1. The power supply must be capable of supplying 16 A. Adjustable voltage range must be from 3 V to 36 V.

Multimeters:

  • Voltmeter 1: Measure the input voltage at VINS+ to VINS–.
  • Voltmeter 2: Measure the output voltage at VOUTS+ to VOUTS–.
  • Ammeter 1: Measure the input current. Connect to the power supply and VIN(+).

Electronic Load:

  • Load 1: Connect to VOUT(+) and VOUT(-). The electronic load must be capable of sinking 12 A.
