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

connect to the board. LTpowerPlay allows the user to

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.

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

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.
