DESCRIPTION
VRCB50CU is the no load line (droopless)
version of the 50A VRM 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 U and 2U form
factors, VRCB50CU is ideal for use in a wide
variety of non-intel processor applications where
high current and low voltage is required.
