General Description

The MAX8660 evaluation kit (EV kit) is a fully assembled

and tested PCB that accepts an input from 2.6V to 6.0V

and provides the output voltages and power-manage-

ment features used by applications processors. The

MAX8660 integrates four step-down DC-DC regulators

and four LDO linear regulators. Additional features

include on/off control for outputs, low-battery detection,

reset output, and a 2-wire I

C serial interface.

The MAX8660 evaluation system (EV system) includes

a MAX8660 EV kit and a Maxim CMAXQUSB+ serial-

interface board. The CMAXQUSB+ board connects to a

PC’s USB port and allows the transfer of I

C to the

MAX8660 EV kit.

The MAX8660 EV kit comes with the MAX8660 installed,

but can also be used to evaluate the MAX8660A,

MAX8660B, and MAX8661.

Quick Start

Recommended Equipment

• Computer with USB port running Windows

98SE/2000/XP

• CMAXQUSB+ interface board

• USB A-to-B cable (included with MAX8660 EV system)

• 2.6V to 6.0V power supply capable of supplying 4A

• Voltmeters

• Loads

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.

Procedure

The MAX8660 EV kit comes with Windows-compatible

software that allows easy evaluation of the I

C serial

interface. This software requires the CMAXQUSB+

interface board. Alternatively, the MAX8660 EV kit can

be evaluated with a user-supplied I

C master, or it can

be partially evaluated (at power-up default voltages

only) without an I

C master. This document assumes

that the CMAXQUSB+ interface board is being used.

The MAX8660 EV kit is fully assembled and tested.

Follow the steps below to verify board operation.

Note: Do not turn on the power supply until all connec-

tions are completed.

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

load the latest version of the EV kit software.

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) Enable outputs V1, V2, and V5 by placing the

shunts across pins 2-3 of JU1, JU2, and JU4 of the

MAX8660 EV kit.

4) Place the shunt of JU3 across pins 1-2 to allow soft-

ware control of REG3 and REG4 enables.

5) Select the desired V1 and V2 output voltage with

JU5 and JU6 (see Table 1).

6) Place the shunt of JU7 across pins 1-2 to set the

C address to 0x68.

7) Preset the power supply to 3.8V. Turn the power

supply off.

8) Connect the positive power-supply terminal to the

EV kit pad labeled IN.

9) Connect the power-supply ground terminal to the

MAX8660 Evaluation Kit/Evaluation System
