Description
LTM4677EY Dual 18A or Single 36A µModule Regulator
With Digital Power System Management
Demonstration circuit 2066A is a dual-output, high ef-ficiency, high density, µModule regulator with 4.5V to 16V input range. Each output can supply 18A maximum load current. The demo board has a LTM®4677 µModule regulator, which is a dual 18A or single 36A step-down regulator with digital power system management. Please see the LTM4677 data sheet for more detailed information.
DC2066A powers up to default settings and produces power based on configuration resistors without the need for any serial bus communication. This allows easy evaluation 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 LTC’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.
GUI Download
The software can be downloaded from: http://www.linear.com/ltpowerplay
For more details and instructions of LTpowerPlay, please refer to LTpowerPlay GUI for LTM4677 Quick Start Guide.
Design files for this circuit board are available at http://www.linear.com/demo/DC2066A

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 LTM4677 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.
Demonstration circuit 2066A is easy to set up to evaluate the performance of the LTM4677EY. 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 1.0V output load between VOUT0 and GND (Initial load: no load).
3. Connect the 1.8V output load between VOUT1 and GND (Initial load: no load).
4. Connect the DVMs to the input and outputs. Set default jumper position: SW1: ON; SW2: ON.
5. Turn on the input power supply and check for the proper output voltages. VOUT0 should be 1.0V ±1%, and VOUT1 should be 1.8V ±1%.

Ltpowerplay softWare GuiLTpowerPlay is a powerful Windows based development environment that supports Linear Technology power system management ICs and μModules, including the LTM4675, LTM4676, LTM4677, LTC3880, LTC3882, 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 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 DC1613A USB-to-SMBus controller to communicate with one of many potential targets, including the LTM4675, LTM4676, LTM4677, 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 documenta-tion. The LTpowerPlay software can be downloaded from:
http://linear.com/ltpowerplay
To access technical support documents for LTC Digital Power Products visit Help. View online help on the LTpowerPlay menu.

Ltpowerplay Quick start GuiDeThe following procedure describes how to use LTpowerPlay to monitor and change the settings of LTM4677.
1.Download and install the LTpowerPlay GUI:
http://linear.com/ltpowerplay
2. Launch the LTpowerPlay GUI.
a. The GUI should automatically identify the DC2066A. The system tree on the left hand side should look like this:
b. A blue message box shows for a few seconds in the lower left hand corner, confirming that LTM4677 is communicating:
c. In the Toolbar, click the “R” (RAM to PC) icon to read the RAM from the LTM4677. This reads the configuration from the RAM of LTM4677 and loads it into the GUI.
Then, click the “W” (PC to RAM) icon to write these register values to the LTM4677. 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.
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:
