Vista PC

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.

•

+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.

7) Set the VIN power supply and enable its output.

8) Start the MAX17065 program by opening its icon in

the Start menu.

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.

9) Normal device operation is verified when CMAXQUSB

HW: Connected. MAX17065 device connected. is

displayed at the bottom left of the MAX17065 EV

kit window.

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.

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).

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

MAX17065 Evaluation Kit

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.

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.

Setting TEST1 and TEST0 checkboxes prevents the

VL, VH, VP, and VN outputs. In this mode, the output

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.

Evluates:MAX17065

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

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.

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.

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.

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.

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.

Simple I C/SMBus Commands

There are two methods for communicating with the

MAX17065: through the normal user-interface panel

(Figure 2) or through the I²C/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 I²C/SMBus commands.

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.

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’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.

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 provides an on-board I²C/SMBus

interface and is connected to the computer through the

USB port. The EV kit includes Windows 2000/XP- and

Windows Vista-compatible software that provides a GUI

for control of the MAX17065’s output voltages, switch-

ing frequency, operating mode, current limit, and SMPS

and charge-pump enables. The MAX17065 EV kit oper-

ates from a +2.3V to +4.5V single power supply.

*Default position.

User-Supplied I²C/SMBus Interface

To use the MAX17065 EV kit with a user-supplied

I²C/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 I²C/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.
