Altera Corporation introduced a 30A PowerSoC DC-DC step-down converter to its portfolio of Enpirion power solutions for FPGAs. The EM1130 is the first in a family of integrated digital DC-DC step-down converters that will provide power management for Altera's Generation 10 FPGAs, specifically for Arria 10 and Stratix 10 FPGA core and transceiver power supply rails.

The result of the acquisition of the Enpirion Inc. power IC company by Altera in 2013, the EM1130 digital power management device represents a milestone in Altera's endeavour to bring optimised power solutions to the programmable logic market.

The EM1130 offers the industry's most dense footprint, and offers high, tight output regulation and fast transient response. These features enable FPGA-based systems to meet the most 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 significant power savings 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.

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

"As a building block for a more intelligent system, the EM1130 architecture allows communication between the FPGA, the system power supply, and the rest of the customer's application providing the most flexible configuration, that can speed time-to-market with lower risk," said Mark Davidson, general manager of Altera's Power Business unit.
