DEMO MANUAL DC2672A-A LTM4664 48VIN, Dual 25A Module Regulator With Digital Power System Management DESCRIPTION Demonstration circuit 2672A-A is a complete non-isolated 48V input, dual-output, high efficiency, high density Module regulator with 30V to 58V input range. Each output can supply 25A maximum load current. The demo board has a LTM4664 Module 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. the GUI software LTpowerPlayTM 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. 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 evaluation of the DC/DC converter.

Refer to Figure2 for the proper measurement equipment setup and follow the procedure below. 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. 1.With power off, connect the input power supply to VIN (30V-58V) and GND (input return). 7.Connect the dongle and control the output voltages from the GUI. See "LTpowerPlay GUI for the LTM4664 Quick Start Guide" for details. 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 default jumper position: SW1: ON; SW2: ON; SW3: ON; JP1: OFF; JP2: EXT. Note: When measuring the output or input voltage ripple, do not use the long ground lead on the oscilloscope probe. See Figure3 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. 5.Turn on the input power supply and check for the proper output voltages. VOUT0 should be 1.0V0.5%, and VOUT1 should be 1.0V0.5%. Rev. 0 2 DEMO MANUAL DC2672A-A QUICK START PROCEDURE Figure2.

LTpowerPlay Main Interface Rev. 0 6 DEMO MANUAL DC2672A-A QUICK START PROCEDURE LTpowerPlay Quick Start Procedure The following procedure describes how to use LTpowerPlay to monitor and change the settings of LTM4664. 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: 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 communicating: Then, click the "W" (PC to RAM) icon to write these register 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: 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. 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.
