Demonstration circuit DC3082A-C features the LTM4681: the wide input and output voltage range, high efficiency and power density, high current PolyPhase® single output DC/DC step-down μModule® regulator with digital power system management. DC3082A-C is configured as 16-phase single output using 4× LTM4681. The factory default input voltage is 12V typical, output voltage is 1V at 480A typical or 500A peak with recommended 400LFM forced airflow. The demo board output voltages can be adjusted from 0.6V to 1V. Programming the output voltages to any value that is greater than 1V, requires derating output current based on thermal derating curves provided in the data sheet of the LTM4681. Heat sink or other appropriate electronic cooling systems can also be used in conjunction with forced airflow to further optimize the output power when the output is on and loaded with maximum output current. The factory default switching frequency is preset at 350kHz typical. DC3082A-C comes with PMBus interface and digital power system management functions. An onboard 12-pin connector is available for users to connect the dongle DC1613A to the demo board, provides an easy way to communicate and program the part using LTpowerPlay® software development tool. LTpowerPlay software and I2C/PMBus/SMBus dongle DC1613A allows users to monitor real time telemetry of input and output voltages, input and output current, switching frequency, internal IC die temperatures, power stage component temperatures and fault logs. Programmable parameters include device address, output voltages, control loop compensation, switching frequency, phase interleaving, DCM or CCM mode of operation, digital soft-start, sequencing and time based shutdown, fault responses to input and output overvoltage, output overcurrent, IC die and power component overtemperature. The LTM4681 is available in a thermally enhanced, low profile 330-Lead (15mm × 22mm × 8.17mm) BGA package. It is recommended to read the data sheet and the demo manual of LTM4681 prior to use or making any hardware changes to DC3082A-C. LTpowerPlay software can be downloaded here.

The DC3097A-KIT is a demonstration system for the LTC2980-24 for the 24-channel I2C/SMBus/PMBus Power System Manager (PSM) with EEPROM. It consists of 4 circuit boards, namely one DC3094A board and three DC1361B boards. The LTC2980-24 monitors and controls 24 power supply rails which are provided by three DC1361B power supply boards that plug into the DC3094A. The system demonstrates the ability of the LTC2980-24 to sequence, trim, margin, supervise, monitor, and log faults for the twenty-four power supplies. Together these four boards form a sophisticated, 24-channel, digitally programmable and digitally managed power supply system. The board set contains twenty-four independent power supply rails, by having the three DC1361B boards. All 24 rails are based on LTM4603 DC/DC μModule® switching regulators. The DC1361B board is pre-configured with output voltages ranging from 0.8V to 3.3V. The power supply channels may be reconfigured to different output voltages by changing the feedback resistors. The LTC2980-24 can be configured to monitor current on odd numbered channels. The DC1361B board has been designed to allow the user to enable this feature on Channel 7. In this configuration, Channel 7 measures the current on Channel 6’s 1V output. The LTpowerPlay® graphical user interface (GUI) supports this demonstration system and enables complete control of all the features of the LTC2980-24. Together, the LTpowerPlay software and DC3094A hardware system create a powerful development environment for designing and testing configuration settings of the LTC2980-24. LTpowerPlay stores these settings in the LTC2980-24 internal EEPROM or in a project file. The software displays all the configuration settings and real time measurements from the Power System Management IC. Telemetry allows easy access and decoding of the fault log created by the LTC2980-24. The board comes pre-programmed with the EEPROM values appropriate for the twenty-four power supply rails.
