DEMO MANUAL DC2702A-A LTM4700EY Dual 50A or Single 100A Module Regulator With Digital Power System Management DESCRIPTION Demonstration circuit 2702A-A is a dual-output, high efficiency, high density, Module(R) regulator with 4.5V to 16V input range. Each output can supply 50A maximum load current. The demo board has a LTM(R)4700 Module regulator, which is a dual 50A or single 100A step-down regulator with digital power system management. Please see LTM4700 data sheet for more detailed information. 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. DC2702A-A powers up to default settings and produce 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(R) onto your PC and use ADI's For more details and instructions of LTpowerPlay, please refer to LTpowerPlay GUI for LTM4700 Quick Start Guide.

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 (4.5V-16V) and GND (input return). 7.Connect the dongle and control the output voltages from the GUI. See "LTpowerPlay GUI for the LTM4700 Quick Start Guide" for details. 2.Connect the 1.0V output load between VOUT0 and GND (Initial load: no load). 3.Connect the 1.5V output load between VOUT1 and GND (Initial load: no load). 4.Connect the DVMs to the input and outputs. Set default jumper position: JP1: ON; JP2: ON; JP3: ON. 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 1.5V 0.5%. 2 Note: Internal bias circuit is enabled when VIN >7V and JP3 is ON. 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. Rev.

A DEMO MANUAL DC2702A-A LTPOWERPLAY SOFTWARE GUI LTpowerPlay is a powerful Windows based development environment that supports Analog Devices power system management ICs and Modules, including the LTM4675, LTM4676, LTM4677, LTM4678, LTC3880, LTC3882 and LTC3883. 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 present) in order to build a multichip 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, 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 documentation. The LTpowerPlay software can be downloaded from: LTpowerPlay To access technical support documents for Analog Devices Digital Power Products visit the LTpowerPlay Help menu. Online help also available through the LTpowerPlay. Figure13. LTpowerPlay Main Interface Rev. A 7 DEMO MANUAL DC2702A-A 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 DC2702A. 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 LTM4700 is communicating: Then, click the "W" (PC to RAM) icon to write these register values to the LTM4700. After finishing this step, you will see the output voltage will change to 0.8V. If the write is successful, you will see the following message: c. In the tool bar, click the "R" (RAM to PC) icon to read the RAM from the LTM4700. This reads the configuration from the RAM of LTM4700 and loads it into the GUI. d. If you want to change the output voltage to a different value, like 0.8V. In the Config tab, type in 0.8 in the VOUT_COMMAND box, like this: 8 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. Rev.
