DESCRIPTION
The VR110 Series is designed to meet the fast load transients
required by Intel
®
Xeon
®
processors and is fully compliant
with the latest Intel
®
VRM 11.0 specifications. High efficiency
of 84% at full load for reduced power dissipation simplifies
system thermal management. Available in 2U, 1.5U, 1U and
new 0.66U form factors, the VR110 Series is ideal for use in
a wide variety of server applications.
