The KIT34704BEPEVBE operates with a single power supply from 2.7 to 5.5V and is
controlled via I2C with the help of an USB-I2C bridge. Applying Input power supply will
start up the VG regulator, set switching frequency and soft start and finally turn on
REG2, REG3 and REG4 in stand alone mode, all other features can only be controlled
via I2C.

9.1 Jumper Connections

9.2 Input/Output power supply terminal blocks

A three-pin terminal block serves as input terminal for the main power between 2.7 to

5.5V to operate the KIT34704BEPEVBE, as well as providing access to the reference

voltage VDDI generated by the MC34704B to supply configuration voltages.

Regulator 2 through 8 use a two-pin terminal block to provide each GND reference and
VOx respectively. To learn how to configure the output voltage on each regulator, please
refer to the MC34704 datasheet that can be found at www.http://freescale.com

The following diagram shows each of the terminals and its respective output voltage
identificator.

9.3 Starting up the KIT34704BEPEVBE

To Start working with the KIT34704BEPEVBE, provide an input voltage between 2.7 to

5.5V connecting the (+) probe to the VIN terminal and the (-) probe to the GDN terminal

on the Input power terminal block. Turn on the power supply and the LEDRST should
turn on.

At this moment the three stand alone regulators (REG2, REG3 and REG4) should be
providing pre-configured output voltage. To operate the rest of the MC34704B functions,
it is necessary to use I2C communication.

Section 11 will discuss how to interact with the KIT34704BEPEVBE using the Graphical
User Interface developed by freescale to fully operate the MC34704B.

10 KITUSBI2CEVME - Using Hardware

The KITUSBI2CEVME Demo Board provides a way of communicating a PC with
KIT34704EPEVBE or any device that uses I2C or SPI communication protocols.

10.1 Jumper Connections

10.1.1 J9

It is used to set the pull-up voltage of the I2C communication device.

• Pins 1 & 2 (Pin 3 open): set the I2C pull-up resistors at 3.3V

• Pins 2 & 3 (Pin 1 open): set the I2C pull-up resistors at 5V

• Pin header open: Leave the I2C pull-up resistors open. The slave device should pull
up SCL2 and SDA2 signals to a voltage of 3.3V or 5V

10.1.2 J8

This jumper is to enable the status indicator LED. The LED is ON when any operation
is being performed by the MCU.

KITUSBI2CEVME - Using Hardware

10.1.3 J1

The J1 jumper should be disconnected only while JB8 is being programmed. Since the
MCU is already programmed, J1 should be connected all the time, so the board
operates properly. It is not recommended to program the JB8 due to pre loaded program
will be erased and it will not longer operate correctly.

A graphical user interface has been developed to allow the user to fully interact with the
KIT34704BEPEVBE using a Windows XP based computer.

11.1 Installing the KIT34704B GUI and KITUSBI2CEVME driver

Before connecting the KITUSBI2CEVME, install the Graphical User interface by double
clicking into the Setup.exe file provided on the CD included with the kit; follow the
instructions until the software is fully installed. Microsoft Frameworks 2.0 is required, if
it is not previously installed the software will perform this installation prior to the
MC34704 GUI software.

Connect the KITUSBI2CEVME to the USB port on the host computer for the first time,
and the PC will try to recognize the USB device; when the driver selection window
appears select the option “Install from a list or specific Location”.
