The Intel® Enpirion® EM2280 is a fully integrated high-efficiency 80 A DC-DC step-down digital PowerSoC. The device delivers an outstanding combination of power density and conversion efficiency. The EM2280 integrates power switches, inductor, gate drive, controller, and compensation in a small 23 mm x 18 mm QFN package. The EM2280 is PMBus version 1.3 compatible, which enables customization of the device settings including output voltage, fault thresholds, and warnings depending on application needs.

The EM2280 features a state machine based digital control loop that enables a combination of very fast load step response with low ripple, low jitter steady state operation.  The non-linear transient loop reduces output capacitor requirements and is stable with all ceramic implementations.

With full integration of all DC-DC components into the package, the EM2280 is designed, characterized, and qualified as a complete power system, resulting in a low-risk solution with low failure in time (FIT) rates. The EM2280 will dramatically improve the system reliability versus discrete power supply solutions. Reduction of bulk output capacitance further increases system-level reliability.

Excellent thermal performance and custom designed magnetics enhances efficiency and enables the EM2280 to deliver 80 A continuous operating current across the full industrial operating temperature range for FPGA core voltage levels. The proprietary digital power conversion loop of the controller in the EM2280 is designed to meet the precise voltage and fast transient requirements of core rails of high-performance FPGAs, ASICs, DSPs, and processors within a total solution size of 650 mm².
