  • MAX17692AEVKIT#
  • One 18V to 36V DC, 0.65A power supply
  • 3.25W resistive load with 0.65A sink capacity
  • Four digital multimeters (DMM) Warning:
  • Do not turn on the power supply until all connections are completed.
  • Do not touch any part of the circuit with bare hands or conductive materials when powered up.
  • Make sure all high-voltage capacitors are fully discharged before handling. Allow 5 minutes after disconnecting the input power source before touch- ing circuit parts. Equipment Setup and Procedure 1) Set the power supply to +24V DC. Disable the power supply output. 2) Connect the positive terminal of the power supply to the VIN PCB pad and the negative terminal to the nearest PGND PCB pad. Connect the positive termi- nal of the electronic load to the VOUT PCB pad and the negative terminal to the nearest GND0 PCB pad. 3) Connect a DMM configured in voltmeter mode across the VOUT PCB pad and the nearest GND0 PCB pad. 4) Verify that shunt is installed across pins 1–2 on jumper JU1 for proper operation. See Table 1 for details. 5) Verify that shunts are not installed for pins 1–2 on both jumpers JU2 and JU3. See Table 2 and Table 3 for details. 6) Enable the power supply. 7) Verify that the output voltmeter displays 5V and, if required, measure the output current using a DMM in Ammeter mode. 8) If required, vary the input voltage from 18V to 36V and the load current from 1mA to 0.65A, and verify that output voltage is 5V.
