The LTC2980 is a 16-channel Power System Manager used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry and create fault logs. PMBus commands support power supply sequencing, precision point-of-load voltage adjustment and margining. DACs use a proprietary soft-connect algorithm to minimize supply disturbances. Supervisory functions include overvoltage and undervoltage threshold limits for sixteen power supply output channels and two power supply input channels, as well as over and under temperature limits. Programmable fault responses can disable the power supplies with optional retry after a fault is detected. Faults that disable a power supply can automatically trigger black box EEPROM storage of fault status and associated telemetry. An internal 16-bit ADC monitors sixteen output voltages, two input voltages, and die temperature. In addition, odd numbered channels can be configured to measure the voltage across a current sense resistor. A programmable watchdog timer monitors microprocessor activity for a stalled condition and resets the microprocessor if necessary. A single wire bus synchronizes power supplies across multiple LTC Power System Management (PSM) devices. Configuration EEPROM with ECC supports autonomous operation without additional software.

The DC2198A is a demonstration system for the LTC®2980 16-channel I2C/SMBus/PMBus power system manager with EEPROM. The LTC2980 monitors and controls 16 power supply rails. The DC2198A demonstrates the ability of the LTC2980 to sequence, trim, margin, supervise, monitor, and log faults for sixteen power supply rails. Each power supply channel’s output voltage is monitored and the LTC2980 monitors its own internal die temperature. The DC2198A is a single circuit board that contains sixteen independent power supply rails. The board employs sixteen LTC3405A 300mA switch-mode regulators, which are configured to be controlled by the LTC2980. The LTC2980 is available in a BGA package and contains two LTC2977 devices. This board provides a sophisticated 16-channel digitally programmable power supply system. The rail voltages are programmable within the trim range shown in the Performance Summary. This demonstration system is supported by the LTpowerPlay™ graphical user interface (GUI) that enables complete control of all the features of the LTC2980. Together, the LTpowerPlay software and DC2198A hardware system create a powerful development environment for designing and testing LTC2980 configuration settings. These settings can be stored in the device’s internal EEPROM or in a file. This file can later be used to order pre-programmed devices or to program devices in a production environment. The software displays all of the configuration settings and real time measurements from the LTC2980. Telemetry allows easy access and decoding of the fault log created by the LTC2980. The board comes pre-programmed with the EEPROM values appropriate for the sixteen power supplies used on the DC2198A. Just plug and play! Multiple DC2198A boards can be cascaded together to form a high channel count power supply (see MultiBoard Arrays). This cascaded configuration demonstrates features of the LTC2980 which enable timing and fault information to be shared across multiple ICs. The user can configure up to four DC2198A boards, thereby controlling up to 64 separate power supply rails. Larger arrays of LTC2980s are supported through programmable I2C base address or bus segmentation. The DC2198A demo board can be powered by an external power supply, such as a +12VDC supply. Communication with the software is provided through the DC1613 USB-toI2C/SMBus/PMBus Controller.
