2) Install all shunts as recommended in Table 1.

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

J6 and your Windows-based PC.

4) Apply a 3.7V supply (set for 100mA current limit)

through an ammeter (set for 10mA range) across

the SYS and GND2 terminals of the EV kit. Turn the

supply on.

Quick Start

Follow this procedure to familiarize yourself with the EV kit.

Note: In the following sections, software-related items are

identified by bolding. Text in bold refers to items directly

from the EV kit software. Text in bold and underlined

refers to items from the Windows operating system.

5) Open the GUI and press the Connect button in the

upper left corner. Wait for the device to respond, and

in the Synchronize window, press the Read and

close button.

6) Press the on-key (SW1) for approximately 1 second,

then release the on-key.

7) Conﬁrm with the ammeter that the quiescent current

is approximately 37.5µA.

8) Connect a DVM to SBB0, SBB1, and SBB2. For the

MAX77680A, 1.8V, 1.2V, and 3.3V appear, respec-

tively. For the MAX77681A, 1.8V, 3.3V, and 5.0V

appear, respectively.

Procedure

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

below to verify board operation.

This concludes the Quick Start procedure. Users are now

encouraged to explore the device and its register settings

with the GUI. During general device evaluation, set the

ammeter range to greater than or equal to 1A to minimize

the impact of its series resistance.

1) Visit the product webpage at www.maximinte-

grated.com/max77680evkit and navigate to Design

Resources to download the latest version of the EV

kit software. Save the EV kit software to a temporary

folder and decompress the ZIP ﬁle.

EV Kit Features

Software

The graphical user interface (GUI) software allows for

quick, easy, and thorough evalution of the MAX77680/

MAX77681.

On-Key Options

For applications that require the IC to enable with a user-

interactable switch, the EV kit comes with two common

types: the push-button (momentary) and the slide-switch

(persistent). The active-low enable pin (nEN) has an inter-

nal pullup resistor. Select between either switch with the

jumper J5. Refer to the data sheet for more information on

configuring the IC for momentary or persistent switches.

The GUI is designed to have individual tabs for each

functional block of the device (MAX77680/MAX77681,

Interrupts/Status, and SIMO) and an additional tab for

controlling EV kit hardware (Load Control). See Figure 6

for a screenshot of the GUI upon first opening.

Installation

Electronic Load

Visit the product webpage at www.maximintegrated.

com/max77680evkit and navigate to Design Resources

to download the latest version of the EV kit software. Save

the EV kit software to a temporary folder and decompress

the ZIP file.

The EV kit comes with an electronic load that allows

the user to easily evaluate the SIMO regulators. An on-

board DAC and op-amp configuration set the load current

2

through I C, and J201, J203, and J205 connects the load

to the output of SBB0, SBB1, and SBB2, respectively.

Emulate SYS loading by removing J201 and connect-

ing pin 1 of the header to VSYS with a wire. To exercise

the load transient response of a regulator, remove J200,

J202, or J204 and connect a signal generator to the gate

of the load MOSFET (pin 2 of the header). Drive the

MOSFET gate with a signal between ~1V (off) and ~3V

(fully on) to apply transients to the output of the regulator

(assuming J201, J203, J205, or J207 is installed). Note

that there is a 1Ω sense resistor that has test point access

(called VIL_SBBx) that allows for a 1:1 conversion of load

current to voltage.

Windows Drivers

Upon connection of a micro-USB cable between your PC

and the EV kit for the first time, wait a few minutes for

Windows to automatically install the necessary drivers.

Graphical User Interface (GUI) Details

2

The GUI drives I C-communication with the EV kit.

Every control in the GUI (excluding the Load Control)

corresponds directly to a register within the MAX77680/

MAX77681. Refer to the AN6473: MAX77680/MAX77681

I²C-Compatible Serial Interface Implementation Guide

for a complete description of the registers. The Load

Control and tabs provide additional functionality with the

EV kit.

value (mA) and press the Enable button. Shuffle through

the modes to exercise different load conditions. The offset

and gain values are set by Maxim and do not need to be

altered.

Load Control Tab

The Load Control tab contains controls for setting load

on the SIMO outputs. The GUI is capable of setting

steady-state, transient, and random load currents. To set
