Required Equipment
•
MAX17553CEVKIT#
•
One 13V to 60V DC, 50mA power supply
•
One 5V DC, 5mA power supply
•
Load resistors capable of sinking up to 50mA at 12V
•
Digital multimeters (DMM)
EV Kit Setup and Procedure
A typical bench setup for the MAX17553C EV kits is shown in
The EV kit is fully assembled and tested. Follow the steps to verify and test the operation of individual converters.
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 five minutes after disconnecting the
input power source before touching circuit parts.
Equipment Setup and Procedure
1. Set the power supply to a voltage between 20V and 60V. Disable the power supply.
2. Connect the positive terminal of the 60V power supply to the VIN PCB pad and the negative terminal to the nearest
GND PCB pad. Connect the positive terminal of the 50mA load to the VOUT PCB pad and the negative terminal to
the nearest GND PCB pad.
3. Set the digital multimeter to voltage mode and connect across the VOUT PCB pad and the nearest GND PCB pad.
4. Connect the positive terminal of the 5V power supply to the VEXT PCB pad and the negative terminal to the nearest
GND PCB pad.
5. Enable both power supplies.
6. Verify that the output voltmeter displays 12V and, if required, measure the output current using a DMM in ammeter
mode.
7. If required, vary the input voltage from 14V to 60V and the load current from 0mA to 50mA, then verify that the output
voltage is 12V with respect to GND.
