Description
LTM4676EY
High Efficiency, PolyPhase
®
, DC/DC
Step-Down μModule Regulator with
PMBus Power System Management
Demonstration circuit 2106A-B is a high efficiency, high
density, µModule regulator with 4.5V to 16V input range.
The output voltage is adjustable from 0.5V to 1.8V, and it
can supply 130A maximum load current. The demo board
has 1×LT M
®
4676 and 3×LTM4630 µModule regulators.
The LTM4676 is a dual 13A or single 26A step-down
regulatorwithPMBus power system management, and the
LTM4630 is a dual 18A or single 36A step-down regulator.
Please see LTM4676 and LTM4630 data sheets for more
detailed information.
DC2106A-B powers up to default settings and produces
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, download
the GUI software LTpowerPlay™ onto your PC and use

LT C ’s I2C/SMBus/PMBus dongle DC1613A to connect to
the board. LTpowerPlay allows the user to reconfigure the
part on the fly and store the configuration in EEPROM,
and view telemetry of voltage, current, temperature and
fault status.

Quick start proceDure
Demonstration circuit 2106A-B is easy to set up to evalu-
ate the performance of the LTM4676EY. 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 to 16V) and GND (input return).
2. Connect the output load between VOUT0 and GND (Initial
load: no load).
3. Connect the DVMs to the input and outputs. Set default
switch position: SW1: ON; SW2: ON.
4. Turn on the input power supply and check for the proper
output voltages. VOUT0 should be 1V ±1%.
5. Once the proper output voltages are established, ad-
just the loads within the operating range and observe
the output voltage regulation, ripple voltage and other
parameters.
6. Connect the dongle and control the output voltages
from the GUI. See “LTpowerPlay GUI for the LTM4676
Quick Start Guide” for details.
Note: 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.
Connecting a PC to DC2106A-B
You can use a PC to reconfigure the power management
features of the LTM4676 such as: nominal VOUT, margin
setpoints, OV/UV limits, temperature fault limits, sequenc-
ing parameters, the fault log, fault responses, GPIOs and
other functionality. The DC1613A dongle may be plugged
when VIN is present.

LTpowerPlay Software GUI
LTpowerPlay is a powerful Windows based development
environment that supports Linear Technology power sys-
tem management ICs, including the LTM4676, LTC3880,
LTC3883, LTC2974 and LTC2978. 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 mul-
tichip configuration file that can be saved and reloaded at a
latertime.LTpowerPlayprovidesunprecedenteddiagnostic
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
DC1613A USB-to-SMBus controller to communicate with
one of many potential targets, including the LTM4676, the
LTC3880 and the 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 documentation. The LTpowerPlay
software can be downloaded from:
http://linear.com/ltpowerplay

Quick start proceDure
2. Launch the LTpowerPlay GUI.
a. The GUI should automatically identify the DC2106A-B.
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 LTM4676 is
communicating:
c. In the Toolbar, click the “R” (RAM to PC) icon to read the
RAM from the LTM4676. This reads the configuration
from the RAM of LTM4676 and loads it into the GUI.
d. If you want to change the output voltage to a different
value, like 1.5V. In the Config tab, type in 1.5 in the
VOUT_COMMAND box, like this:
Then, click the “W” (PC to RAM) icon to write these
register values to the LTM4676. After finishing this step,
you will see the output voltage will change to 1.5V.
If the write is successful, you will see the following
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.
