Introduction
This Evaluation Board demonstrates the capability of the MC34704B as a multi-channel
power management IC (PMIC) meant to address power management needs for various
multimedia application microprocessors. It provides 5 independent voltages through
terminal block connector for an easier out-of-the-box evaluation. A single Terminal block
connector for input power supply allows the user to supply the board with either a
external DC power supply or a Li-Ion battery to fully evaluate the performance
accordingly.
The KIT34704BEPEVBE has the ability to program the switching frequency of VG and
regulators 2 through 5 as well as the default soft start timing for all regulators during
startup by changing few external components. All other features can be programmed
via I2C communication using a standard 100mils 4-pin header to communicate with
either the USB-I2C bridge included in this package or with any other I2C communication
device preferred by the user.

KIT34704BEPEVBE - Using Hardware
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.

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.

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

J8
This jumper is to enable the status indicator LED. The LED is ON when any operation
is being performed by the MCU.

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”.
Figure 11. KITUSBI2CEVME Driver installation Window.
In the next window browse the path where you installed the KIT34704GUI and click
Next. At this time, the Computer should recognize the KITUSBI2CEVME board and be
ready to use the Graphical User Interface to control the KIT34704xEPEVBE
