DESCRIPTION

LTM4664

48VIN, Dual 25A µModule Regulator

With Digital Power System Management

Demonstration circuit 2672A-A is a complete non-iso-

lated 48V input, dual-output, high efficiency, high density

µModule regulator with 30V to 58V input range. Each

output can supply 25A maximum load current. The demo

board has a LTM4664 µModule regulator, which is a dual

25A or single 50A step-down regulator with digital power

system management. Please see the LTM4664 datasheet

for more detailed information.

DC2672A-A 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 All registered trademarks and trademarks are the property of their respective owners.

the GUI software LTpowerPlay™onto your PC and use

ADI’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, view

telemetry of voltage, current, temperature and fault status.

QUICK START PROCEDURE

Demonstration circuit 2672A-A is easy to set up to evalu-

ate the performance of the LTM4664. 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

(30V-58V) and GND (input return).

2. Connect the 1.0V output load between VOUT0 and GND

(Initial load: no load).

3. Connect the 1.0V output load between VOUT1 and GND

(Initial load: no load).

4. Connect the DVMs to the input and outputs. Set de-

fault jumper position:SW1:ON;SW2:ON;SW3:ON;

JP1: OFF; JP2: EXT.

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 1.0V±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 LTM4664

Quick Start Guide” for details.

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 Software GUI

LTpowerPlay is a powerful Windows based development

environment that supports Analog Devices power sys-

tem management ICs and μModules, including LTM4675,

LTM4676, LTM4677, LTM4678, LTM4680, LTM4700,

LTM4664, LTC3880, LTC3882, LTC3883 and LTC3884.

The software supports a variety of different tasks. You

can use LTpowerPlay to evaluate Analog Devices ICs by

connecting to a demo board system. LTpowerPlay can

also be used in an offline mode (with no hardware pres-

ent) in order to build a multichip configuration file that

can be saved and reloaded at a later time. L

TpowerPlay

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 DC1613A USB-to-SMBus

controller to communicate with one of many potential tar-

gets, including LTM4675, LTM4676, LTM4677, LTM4678,

LTM4680, LTM4700, LTM4664, LTC3880, LTC3882,

LTC3883 and LTC3884’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 here.

QUICK START PROCEDURE

LTpowerPlay Quick Start Procedure

The following procedure describes how to use LTpow-

erPlay to monitor and change the settings of LTM4664.

1.Download and install the LTPowerPlay GUI:

2. Launch the LTpowerPlay GUI.

a. The GUI should automatically identify the DC2672A-A.

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 LTM4664 is com-

municating:

c. In the Toolbar, click the “R” (RAM to PC) icon to read

the RAM from the LTM4664. This reads the configuration

from the RAM of LTM4664 and loads it into the GUI.

d. If you want to change the output voltage to a differ-

ent 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 regis-

ter values to the LTM4664. 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.
