Analog Devices MAX42410 User Manual

General Description
The MAX42410 evaluation kit (EV kit) provide a proven
design to evaluate the MAX42410 synchronous buck
converter with 10μA quiescent current. The EV kit comes
with a MAX42410AFOB+ (1.5MHz) installed, as well as
various test points and jumpers for evaluation. The EV kit
output voltage is variable and is set to 3.3V. It can be easily
configured to 0.8V to 6V (1.5MHz) or up to 10V (400kHz)
with minimum component changes. The EV kit is designed
to deliver up to 10A with input voltage 4.5V to 36V. The
output voltage quality can be monitored by observing the
PGOOD signal.

Quick Start
Required Equipment
•
MAX42410 EV kit
•
36V, 10A DC power supply (PS)
•
Appropriate resistive load, or an electronic load that
can sink 10A
•
Digital multimeter (DMM)
•
Oscilloscope
Procedure
The EV kit is fully assembled and tested. Do the following
steps to verify board operation:
1. Verify that all jumpers are in their default positions, as
shown in Table
2. Connect the positive and negative terminals of the
power supply to the VSUP and GND test pads,
respectively.
3. Set the power-supply voltage to 14V.
4. Turn on the power supply.
5. Using the DMM, verify the OUT is approximately 3.3V.
6. Verify that the switching frequency is approximately
1.5MHz by monitoring the inductor switching voltage
with the oscilloscope.
7. Turn off the power supply.
8. Connect the positive and negative terminals of the
electronic load to VOUT and GND2, respectively.
9. Set the electronic load to the required current at or
below 10A or use an equivalent resistive load with an
appropriate power rating.
10. Adjust current-limit on the power supply as necessary.
11. Turn on the power supply and electronic load.
12. Verify that voltage across the VOUT and GND2 PCB
pads is 3.3V ± 2%.
