DESCRIPTION
The VR111 Series is designed to meet the fast load transients
required by Intel® Nehalem® processors and is fully compliant
with the latest Intel® VRM 11.1 specifications. High efficiency of
up to 85% at full load for reduced power dissipation simplifies
system thermal management. Available in 2U, 1.5U, 1U and
new 0.66U form factors, the VR111 Series is ideal for use in
a wide variety of server applications.

NOTES
➀ Vin = 12Vdc, Ta = 25ºC, Airflow = 400LFM unless otherwise noted.
➁ The output impedance for VRM 11.1 models (VR111 Series) powering VCORE is
0.8mΩ. VR11FB080CE-C is designed to power VCACHE, which requires 1.4mΩ.
➂ Output ripple voltage is specified when measured with Intel® specified capacitance at the output of the converter.
➃ Transient response is specified with Intel® specified capacitors at the output
of the converter. See recommended output capacitance.
