Description

The Intel® Enpirion® EM2140 is a fully integrated high-efficiency 40A DC-DC step-down digital PowerSoC. The device delivers an outstanding combination of power density and conversion efficiency. The EM2140 integrates power switches, inductor, gate drive, controller, and compensation in a small 11 x 17 mm QFN package. The EM2140 is PMBus version 1.2 compatible, which helps to configure the device settings including output voltage, fault thresholds, and warnings depending on application needs.

With full integration of all DC-DC components into the package, the EM2140 is designed, characterized, and qualified as a complete power system, resulting in a low-risk solution with low failure in time (FIT) rates. The EM2140 will dramatically improve the system reliability versus discrete power supply solutions.

Excellent thermal performance and custom designed magnetics enhances efficiency and enables the EM2140 to deliver 40A continuous operating current across the full industrial operating temperature range. The proprietary digital power conversion loop of the controller in the EM2140 is designed to meet the precise voltage and fast transient requirements of core rails of high-performance FPGAs, ASICs, digital signal processors (DSPs), and processors within a total solution size of 360 mm2.

The EM2140 is footprint-compatible with the EM2120 (20A) and EM2130 (30A) digital PowerSoCs. Learn more about the full family offering at the Digital Power Resource Center.
