VR11CB150CU-1C Datasheet, PDF (1/6 Pages) Murata Power Solutions Inc. – No Load Line Version of Intel® VRM 11.0

DESCRIPTION
The VR11C Series is the no load line (droopless) version
of the VRM 11.0 models where the output voltage stays
constant over the output load range. High efficiency of
85% at full load for reduced power dissipation simplifies
system thermal management. Available in 2U and 1U
form factors, the VR11C Series is ideal for use in a wide
variety of non-Intel^® processor applications where high
current and low voltage is required.
