DESCRIPTION
LTM4700
Single 100A µModule Regulator with
Digital Power System Management
Demonstration circuit 2702B-B is a single output, dual-
phase, high efficiency, high density, µModule
®
regulator
with a 4.5V to 16V input range. The output voltage is
adjustable from 0.5V to 1.8V and can supply 100A maxi-
mum load current. The DC2702B-B demo board has a
LT M
®
4700 µModule regulator, a dual 50A or single 100A
step-down regulator with digital power system man-
agement. Refer to the LTM4700 data sheet for more
detailedinformation.
DC2702B-B powers up to default settings and produces
power based on configuration resistors without serial bus
communication. This feature allows easy evaluation of
the DC/DC converter. To fully explore the extensive power
system management features of the LTM4700, download

reconfigure the part on-the-fly, store the configuration in
EEPROM, view telemetry of voltage, current, temperature
and faultstatus.

QUICK START PROCEDURE
Demonstration circuit 2702B-B is easy to set up to evalu-
ate the performance of the LTM4700EY. See Figure2 for
the proper measurement equipment setup and follow the
procedure below.
1. With power off, connect the input power supply to VIN
(4.5V to 16V) and GND (input return).
2. Connect the 1.0V output load between VOUT0 and GND
(Initial load: no load).
3. Connect the Digital Voltmeters (DVMs) to the input
and outputs. Set default jumper position:
JP1: ON
JP2: ON
JP3: ON
4. Turn ontheinputpowersupplyandcheckfortheproper
output voltages. VOUT0 should be 1.0V ±0.5%.
5. Once the proper output voltages are established,
adjust the loads within the operating range and ob-
serve theoutput voltage regulation, ripple voltage and
otherparameters.
6. Connect the dongle and control the output voltages
fromtheGUI.Formoredetails,refertotheLTpowerPlay
GUI for the LTM4700 Quick Start Guide.
Notes
The internal bias circuit is enabled when VIN >7V and JP3
isON.
When measuring the output or input voltage ripple, do
not use the long ground lead on the oscilloscope probe.
See Figure3 for the proper scope probe technique. Short,
stiff leads need to be soldered to the (+) and (–) terminals
of an output capacitor. The probe’s ground ring needs to
touch the (–) lead, and the probe tip needs to touch the
(+) lead.

A Personal Computer (PC) can be used to reconfigure
the power managementfeatures of the LTM4700, such
as nominal VOUT, marginset points, OV/UV limits, tem-
perature fault limits, sequencing parameters, the fault
log, fault responses, GPIOs and other functionalities. The

LTpowerPlay is a powerful Windows-based development
environment that supports Analog Devices power sys-
tem management ICs and μModule ICs, including the
LTM4675, LTM4676, LTM4677, LTM4678, LTC3880,
LTC3882 and LTC3883. The software supports a variety
of different tasks. You can use LTpowerPlay to evalu-
ate Analog Devices ICs by connecting to a demo board
system. LTpowerPlay can also be used in an offline mode
(with no hardware present) to build a multichip configura-
tion file that can be saved and reloaded later. LTpowerPlay
provides unprecedented diagnostic and debug features. It
becomes a valuable diagnostic tool during board bring-
up to program or tweak the power management scheme

in a system, or to diagnose power issues when bring-
ing up rails. LTpowerPlay utilizes the DC1613A USB-
to-SMBus controller to communicate with one of many
potential targets, including the LTM4675, LTM4676,
LTM4677, LTM4678, LTC3880, LTC3882, LTC3883’s
demo system, or a customer board. The software also
provides an automatic update feature to keep the software
current with the latest set of device drivers and docu-
mentation. The LTpowerPlay software can be downloaded
from LTpowerPlay.

LTpowerPlay QUICK START PROCEDURE
The following procedure describes how to use LTpowerPlay
to monitor and change the settings of LTM4700.
1. Download and install the LTpowerPlay GUI.
2. Launch the LTpowerPlay GUI.
a. The GUI should automatically identify the
DC2702B-B. The system tree on the left-hand side
should look like as shown in the following figure:
b. A green message box shows for a few seconds in
thelowerleft-handcorner,confirmingthatLTM4700
iscommunicating:
c. In the toolbar, click the “R” (RAM to PC) icon to
read the RAM from the LTM4700. This step reads
the configuration from the RAM of LTM4700 and
loads it into theGUI.
d. Ifyou want tochangetheoutput voltage toadifferent
value, 0.8V. In the Config tab, type in 0.8 in the
VOUT_COMMAND box as shown in the following
figure:
e. Then, click the “W” (PC to RAM) icon to write these
register values to the LTM4700. After finishing this
step, the output voltage changes to0.8V.
f. If the write is successful, the following message
will be seen:
g. Changes can be saved into the NVM. In the toolbar,
click the “RAM to NVM” button:
h. Save the demo board configuration to a (*.proj)
file. Click the Save icon and save the file.
