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.

DEMO MANUAL DC2106A-B

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

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.
