1. Description

The EM21xx are a series of PowerSoC synchronous buck converters from the Intel® Enpirion®
Power Solutions family. The EM22xx series feature an advanced digital controller, gate
drivers, synchronous MOSFET switches, and a high performance inductor. Only input and
output filter capacitors and a few small signal components are required for a complete
solution. A PMBus™ version 1.2 compliant interface provides setup, control, and telemetry.

Differential remote sensing and ±0.5% set-point accuracy provide precise regulation over
line, load and temperature variation. Very low ripple further reduces accuracy uncertainty to
provide best in class static regulation for today’s FPGAs, ASICs, processors, and DDR
memory devices.
