MAX77756 Evaluation Kit

Quick Start

Required Equipment

● MAX77756 EV kit

● Windows-based PC

● Power supply

● Ammeter

● Digital voltmeter (DVM)

● Micro-USB cable

identified by bolding. Text in

bold refers to items directly

from the EV kit software.

Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation:

1) Visit

www.maximintegrated.com/evkitsoftware to

download and install the latest version of the EV kit

GUI software. Save the EV kit software to your local

MAX77756 folder and uncompress the ZIP file. Run

the .EXE file that was uncompressed and follow the

on-screen instructions to complete installation.

2) Install the EV kit shunts per Table 1.

3) Apply a power supply set to 0V (100mA current limit)

through an ammeter (10mA range) across the SUP

and GND2 terminals of the EV kit. Turn the supply on

and increase the voltage to 12V. To avoid excessive in-

rush current into the input capacitors of the EV kit, do

not connect a precharged power supply to the input.

See the Input Slew-Rate Limiting section for more in-

formation.

4) Connect a Micro-B USB cable between the EV kit’s

J103 and your Windows-based PC.

5) Open the GUI and press the

Device button in the

menu bar. Press the

Connect button in the Device

button’s drop-down list. Wait for the device to re-

spond, and in the

Synchronize window, press the

Read and close button.

6) Confirm with the ammeter that the quiescent current

is approximately 1.5µA.

7) Confirm with DVM that output voltage is 3.3V.

This concludes the Quick Start procedure. Users are

encouraged to explore the device and its register set-

tings with the GUI. During general device evaluation, set

the ammeter range to ≥ 1A to minimize the impact of its

series resistance. For more information on the GUI, see

the Detailed Description of Software section.
