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.
