Specifications of MAX17480EVKIT+

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The main window of the evaluation software (Figure 1)
displays Address to Send, Data to Send, Last
Address Sent, and Last Data Sent status. In addition,
the GUI allows the user to select Combined Mode,
Core 0, Core 1, and/or North Bridge outputs.
The sliders to the right of each output checkbox corre-
spond with the output-voltage setting for that core. The
Send Data button must be pressed to write the new
output-voltage setting(s) to the MAX17480. The Last
Address Sent and Last Data Sent status helps the
user keep track of the last transmission.
At start-up, the software is configured for combined-
mode operation (Combined Mode checkbox checked).
In combined mode, the MAX17480 ignores Core 1
commands. To configure the software for separate-
mode operation, uncheck the Combined Mode check-
box and follow the instructions in the Separate-Mode
Operation section.
