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 specifi cations. High effi ciency
of 84% at full load for reduced power dissipation simplifi es
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.

NOTES
➀ Backward compatible to VR102B150CU-3C.
➁ VIN = 12Vdc, TA = 25ºC, Airfl ow = 400LFM unless
otherwise noted.
➂ The output impedance is 1.25mΩ.
➃ Output ripple voltage is specifi ed when measured
with Intel® specifi ed capacitance at the output of
the converter.
➄ Transient response is specifi ed with Intel® speci-
fi ed capacitors at the output of the converter.
➅ If remote sense is not required or used, the
Sense(+) and Sense(–) pins must be connected
to Vo(+) and Vo(–) respectively.
➆ 10μF ceramic X5R or X6S.
