Procedure

The MAX17094 EV kit is fully assembled and tested.

Follow the steps below to verify board operation.

Caution: Do not turn on the power supply until all

connections are completed.

1) Verify that a shunt is installed across jumper JU2.

2) Set an external power supply to ≈ +3.3V. Connect

the positive terminal of the power supply to the VIN

pad. Connect the negative terminal of the power

supply to the PGND pads closest to VIN.

3) Turn on the power supply and verify that the step-

up switching regulator output (MAIN) is +8V.

4) Verify that the positive charge-pump supply (VP) is

approximately +24V.

5) Verify that the negative charge-pump supply (VN) is

approximately -8.8V.

6) Verify that the linear regulator output (VLOGIC) is

approximately 2.5V.

7) Visit www.maxim-ic.com/evkitsoftware to down-

load the latest version of the MAX17094 EV kit soft-

ware, MAX17094Rxx.ZIP. Save the EV kit software

to a temporary folder and uncompress the ZIP file.

8) Install the EV kit software on your computer by run-

ning the INSTALL.EXE program inside the tempo-

rary folder. The program files are copied and icons

are created in the Windows Start | Programs menu.

9) Connect the USB cable from the PC to the EV kit

board. A Building Driver Database window pops

up in addition to a New Hardware Found message

when installing the USB driver for the first time. If

you do not see a window that is similar to the one

described above after 30 seconds, remove the

USB cable from the board and reconnect it.

Administrator privileges are required to install the

USB device driver on Windows 2000/XP/Vista.

10) Follow the directions of the Add New Hardware

Wizard to install the USB device driver. Choose the

Search for the best driver for your device option.

Specify the location of the device driver to be

C:\Program Files\MAX17094 (default installation

directory) using the Browse button. During device

driver installation, Windows may show a warning

message indicating that the device driver Maxim

uses does not contain a digital signature. This is not

an error condition and it is safe to proceed with instal-

lation. Refer to the TROUBLESHOOTING_USB.PDF

document included with the software for additional

information.

11) Start the MAX17094 EV kit software by opening its

icon in the Start | Programs menu.

12) Normal device operation is verified when

MAX17094 device connected appears in the

status bar on the MAX17094 EV kit main window

(Figure 1).

13) Verify that the output of the high-speed op amp

(VCOM) is approximately +3.2V.
