MAX20343 Evaluation Kit

10) Use the voltmeter to measure VOUT and confirm that

it is 5.5V ± 3%.

To measure the efficiency of the MAX20343:

11) Remove the shunt jumpers from J1 and J2.

12) Connect the first ammeter in series to the input sup-

ply by attaching the input terminal to pin 1 of J1 and

the output terminal to pin 2 of J1.

13) Connect the second ammeter in series to output load

by attaching the input terminal to pin 1 of J2 and the

output terminal to pin 2 of J2.

14) Attach the load to VOUT and measure the input volt-

age, input current, output voltage, and output current.

Detailed Description of Software

The MAX20343 Evaluation Kit Tool is a GUI that provides

a simple and quick way to test different configuration

settings for the I2C-controlled version of the MAX20343.

The GUI contains several tabs to configure different

parameters of the MAX20343 and a register map to

access all registers.

Connecting to the Hardware

When the GUI is first opened, a splash screen appears. The

splash screen displays the GUI software revision and links

to the Maxim Integrated main website and support website.

It can be disabled by checking the box “Disable Splash.”

After the splash screen closes, the main window opens

to the General tab of the GUI. The GUI starts up assum-

ing all configuration bits are set to 0, so the informa-

tion displayed might not match the values stored in the

MAX20343 until the device is read manually or automati-

cally through polling.
