Product Details

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. Just plug and play!
