Altera's new Enpirian converter

Altera added the 30A EM1130 integrated digital DC-DC converter to its Enpirion family of field-programmable gate arrays (FPGAs). The EM1130 provides power management for Altera's Arria 10 and Stratix 10 FPGA core and transceiver power supply rails.

The EM1130 offers what Altera claims to be the industry's most dense footprint, and high, tight output regulation, and fast transient response. These features enable FPGA-based systems to meet the stringent performance, power budget and solution size requirements. PMBus provides the interface for Altera SmartVID technology which allows the converter to provide the Arria 10 and Stratix 10 FPGAs with a lower voltage (VCC) for efficient power management while maintaining the performance of the specific device speed grade.

Additionally, the PMBus interface allows the EM1130 to communicate with the system to provide telemetry—measurement of key parameters such as current, voltage and temperature.

"With this innovation, we will provide integrated power management for our high-end portfolio," said Jeff Waters, senior vice president and general manager, Altera Business Units. "We are pleased with the progress we've seen in the 18 months following the acquisition of Enpirion, and we expect our customers to continue to benefit from the tight coupling of power and industry-leading FPGA platforms."

The EM1130 delivers significant benefits including:

  • 50 per cent smaller than other modules in its grade, with a 2 to 4 per cent efficiency point improvement enabling customers to increase their system performance
  • A 30 to 50 per cent improvement in telemetry accuracy (current and voltage measurement) allowing customers to extend the performance range of their systems
  • Adaptive control technology that reduces external compensation components and adjusts automatically to provide a robust solution regardless of changing operating conditions
  • Easy-to-use graphical user interface (GUI) that simplifies programming so design engineers have a fast path to an optimised solution

"System architects and designers need to plan for power use earlier for performance-driven applications in order to be able to achieve maximum system performance, while reducing energy consumption and thermal loads. When this is accomplished, the cost of ownership is dramatically reduced not only for Altera's customers, but also for our customers' end users," said Mark Davidson, general manager of Altera's Power Business unit.
