1. Description
The EM22xx family are PowerSoC synchronous Dual Phase buck converters from the Intel®
Enpirion® Power Solutions family. The EM22xx series feature an advanced controller, gate
drivers, synchronous MOSFET switches, and high performance inductors. Only input and
output filter capacitors and a few small signal components are required for a complete
solution.
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.
