MAX17065 Evaluation Kit
General Description
The MAX17065 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount PCB that evaluates the
high-efficiency MAX17065 organic LED (OLED) driver.
The MAX17065 EV kit operates from a +2.3V to +4.5V
single power supply and includes dual switch-mode
power-supply (SMPS) outputs, one LDO, and dual reg-
ulated charge pumps for an OLED panel.
The MAX17065 EV kit provides an on-board I

C/SMBus
™
interface and is connected to the computer through the
universal serial bus (USB) port. The EV kit includes
Windows
®
2000/XP- and Windows Vista
®
-compatible
software that provides a graphical user interface (GUI)
for control of the MAX17065’s output voltages, switching
frequency, operating mode, current limit, and SMPS and
charge-pump enables.

Before beginning, the following equipment is needed:
• MAX170655 EV kit (USB cable included)
• A user-supplied Windows
®
2000/XP or Windows
Vista PC
• +2.3V to +4.5V, 1A power supply (VIN)
• Available USB port
Note:
In the following sections, software-related items
are identified by bolding. Text in
bold
refers to items
directly from the EV kit. Text in
bold and underlined
refers to items from the Windows operating system.
described above after 30 seconds, remove the USB
cable from the board and reconnect it. Administrator
privileges are required to install the USB device dri-
ver on Windows. Refer to the TROUBLESHOOT-
ING_USB.PDF document included with the software
if you have any problems during this step.
6) 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\MAX17065
(default installation
directory) using the
Browse
button.
7) Set the VIN power supply and enable its output.
8) Start the MAX17065 program by opening its icon in
the
Start
menu.
9) Normal device operation is verified when

is
displayed at the bottom left of the MAX17065 EV
kit window.
10) Set the switching frequency = 1.2MHz, negative
SMPS = -4.5V, positive and negative current limits
= 0.7A, positive charge-pump output = +6.5V, and
negative charge-pump output = -4V (Figure 1).

Procedure
The MAX17065 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) Visit
www.maxim-ic.com/evkitsoftware
to down-
load the latest version of the EV kit software,
17065Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
2) Install the EV kit software on your computer by run-
ning the INSTALL.EXE program. The program files
are copied and icons are created in the Windows
Start
menu.
3) Verify that jumpers are in their default positions as
follows:

4) Connect the positive terminal of the VIN power sup-
ply to the VIN pad. Connect the ground terminal of
the VIN power supply to the PGND pad.
5) 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

Detailed Description of Software
User-Interface Panel
The program’s main window (Figure 2) is navigated by
using a mouse or a combination of the Tab and Arrow
keys. The MAX17065 EV kit software provides controls
for the following software-configurable features:
Frequency
and
Mode
selection,
ON Enables, Outputs
configuration,
Faults
detection,
Current Limit
settings,
and
Manufacturer ID/Silicon Revision
detection.
Changes to the controls result in a write operation that
updates the appropriate registers of the MAX17065.
A status bar is also provided at the bottom of the pro-
gram’s main window and is used to verify command
module and device connectivity. A
Device Search
option is located in the
Action
menu bar should the user
want to switch from
Demo Mode
to normal operation.
ON Enables and Test
The
ON2
and
ON1
bits enable/disable the various out-
puts of the MAX17065, according to Table 1. To set
either bit high, check the respective
ON_
checkbox in
the
ON Enables
group box.

can be driven by external voltage sources. Setting
either
TEST_
bit to 1 in the
Test
group box disables the
discharge function. Refer to the MAX17065 IC data
sheet for more information regarding the test bits.
Fault Detection
The MAX17065’s
Faults
read-only register monitors the
OLED controller’s operating state, output, and thermal
faults. When a fault is detected, the corresponding bit is
changed from logic 0 to logic 1 and the font color is
changed to red. Refer to the MAX17065 IC data sheet
for more information regarding the
Faults
register.
Outputs
The MAX17065 allows for software control of the
charge-pump and negative SMPS outputs. Select the
appropriate voltages from the
VL:, VH:,
and
VN:
drop-
down lists to set the desired voltages. The default set-
tings are
VL: -0.5V, VH: +5.5V,
and
VN: -0.5V.
Figure 2. MAX17065 EV Kit Software Main Window
Frequency Selection
The MAX17065 can be operated at either 0.6MHz or
1.2MHz. To set the desired frequency, select the
appropriate radio button in the
Frequency
group box.
The default frequency setting is 0.6MHz, but the EV kit
is designed for 1.2MHz. Component changes are
required when selecting different frequencies. Refer to
the MAX17065 IC data sheet for more information
regarding frequency selection.
Current Limit
The MAX17065 software allows the user to set cur-
rent limits for the negative and positive switching
power supplies. To set the current limits, select the
desired current limit from the
IMAXN:
and
IMAXP:
drop-down lists in the
Current Limit
group box. The
default current-limit settings are
IMAXN: 0.45A
and
IMAXP: 0.45A.
Operating Mode
The MAX17065 can be operated in either
Skip Mode
or
Forced PWM.
To set the desired operating mode,
select the appropriate radio button in the
Mode
group
box. The default operating mode is
Forced PWM.
Refer
to the MAX17065 IC data sheet for more information
regarding modes of operation.

Manufacturer ID/Silicon
Revision Detection
The
ID Register
group box shows the manufacturer ID
and silicon revision information of the MAX17065 IC.
This information is read upon initial start-up.

Simple I
2
C/SMBus Commands
There are two methods for communicating with the
MAX17065: through the normal user-interface panel
(Figure 2) or through the I
2
C/SMBus commands, avail-
able by selecting the
Interface Diagnostic Window
menu item from the
Action
menu bar. The
Maxim
Command Module Interface
window pops up and
includes a
2-wire interface
tab that allows for execu-
tion of simple I
2
C/SMBus commands.
The SMBus dialog boxes accept numeric data in bina-
ry, decimal, or hexadecimal. Hexadecimal numbers
should be prefixed by $ or 0x. Binary numbers must be
exactly eight digits. See Figure 3 for an illustration
of this tool.
The MAX17065 includes dual SMPS outputs (+5.35
fixed positive and -5V to -0.5V adjustable negative),
one LDO (+1.9V/60mA), and dual regulated charge
pumps (+5.5V to +9V positive and -5V to -0.5V nega-
tive) for an OLED panel.

Shutdown Control
The MAX7065 can be placed in shutdown mode
through jumper JU1 (see Table 2). When connected to
GND or left open, the VD output is enabled with four ris-
ing CLK edges. When connected to VDDIO, the
MAX17065’s VD is enabled without a CLK signal.

User-Supplied VDDIO Input
The MAX17065’s VDDIO supply is powered from the
USB port by default. Move the shunt of JU2 to the 2-3
position to apply your own +1.6V to +3.6V power sup-
ply at the VDDIO pad. See Table 3 for jumper JU2 con-
figuration. VDDIO voltage decides the
SHDN
and CLK
logic levels. When CLK is driven by an external signal,
jumper JU2 can be placed in a 2-3 position to allow
external VDDIO voltage.

User-Supplied I
2
C/SMBus Interface
To use the MAX17065 EV kit with a user-supplied
I
2
C/SMBus interface, first move the shunts of JU5 and
JU6 to the 2-3 position. Then connect your SDA and
SCL signals to the corresponding SDA and SCL pads
on the MAX17065 EV kit board.
Note:
The I
2
C/SMBus
interface is not available until VD is enabled by either
SHDN
= VDDIO or four rising CLK edges because SDA
and SCL are pulled up by internal 10kΩ resistors.
