DESCRIPTION
LTM4700EY
Dual 50A or Single 100A µModule Regulator
With Digital Power System Management
Demonstration circuit 2702A-A is a dual-output, high
efficiency, high density, µModule regulator with 4.5V to
16V input range. Each output can supply 50A maximum
load current. The demo board has a LTM4700 µModule
regulator, which is a dual 50A or single 100A step-down
regulator with digital power system management. Please
see LTM4700 data sheet for more detailed information.
DC2702A-A powers up to default settings and produce
power based on configuration resistors without the need
for any serial bus communication. This allows easy evalu-
ation of the DC/DC converter. To fully explore the extensive
power system management features of the part, down-
load the GUI software LTpowerPlay™onto your PC and use

the board. LTpowerPlay allows the user to reconfigure the
part on the fly and store the configuration in EEPROM, view
telemetry of voltage, current, temperature and fault status.

QUICK START PROCEDURE
Demonstration circuit 2702A-A is easy to set up to evalu-
ate the performance of the LTM4700EY. Refer to 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-16V) and GND (input return).
2. Connect the 1.0V output load between VOUT0 and GND
(Initial load: no load).
3. Connect the 1.5V output load between VOUT1 and GND
(Initial load: no load).
4. Connect the DVMs to the input and outputs. Set default
jumper position: JP1: ON; JP2: ON; JP3: ON.
5. Turn on the input power supply and check for the
proper output voltages. VOUT0 should be 1.0V ±0.5%,
and VOUT1 should be 1.5V ±0.5%.
6. Once the proper output voltages are established, adjust
the loads within the operating range and observe the
output voltage regulation, ripple voltage and other
parameters.
7. Connect the dongle and control the output voltages
from the GUI. See “LTpowerPlay GUI for the LTM4700
Quick Start Guide” for details.
Note: Internal bias circuit is enabled when VIN >7V and
JP3 is ON.
Note:When measuring the output or input voltage rip-
ple, 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.

LTpowerPlay is a powerful Windows based development
environment that supports Linear Technology power
system management ICs and μModules, including the
LTM4675, LTM4676, LTM4677, LTM4678, LTC3880,
LTC3882 and LTC3883. The software supports a variety
of different tasks. You can use LTpowerPlay to evaluate
Linear Technology ICs by connecting to a demo board
system. LTpowerPlay can also be used in an offline mode
(with no hardware present) in order to build a multichip
configuration file that can be saved and reloaded at a later
time. 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 bringing up rails. LTpowerPlay utilizes the
LTPOWERPLAY SOFTWARE GUI

LTM4676, LTM4677, LTM4678, LTC3880, LTC3882,
LTC3883’s demo system, or a customer board. The soft-
ware also provides an automatic update feature to keep
the software current with the latest set of device drivers
and documentation. 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. TheGUIshouldautomaticallyidentifytheDC2702A.The
system tree on the left hand side should look like this:
b. A green message box shows for a few seconds in the
lower left hand corner, confirming that LTM4700 is
communicating:
c. In the tool bar, click the “R” (RAM to PC) icon to read the
RAM from the LTM4700. This reads the configuration
from the RAM of LTM4700 and loads it into the GUI.
d. If you want to change the output voltage to a different
value, like 0.8V. In the Config tab, type in 0.8 in the
VOUT_COMMAND box, like this:
Then, click the “W” (PC to RAM) icon to write these reg-
ister values to the LTM4700. After finishing this step, you
will see the output voltage will change to 0.8V.
Ifthewriteissuccessful,you willseethefollowing message:
e. You can save the changes into the NVM. In the tool
bar, click “RAM to NVM” button, as following:
f. Save the demo board configuration to a (*.proj) file.
Click the Save icon and save the file. Name it whatever
you want.
