Monolithic VR demonstration board for chipset
and DDR2/3 supply for ultramobile PC (UMPC) applications

Introduction
PM6641 demonstration board order code: STEVAL-ISA050V1 (previously coded as
PM6641EVAL).
The PM6641 demonstration board is a monolithic voltage regulator (VR) module with
internal power MOSFETs, specifically designed to supply DDR2/3 memory and chipset in
ultramobile PC and real estate constrained portable systems.
It integrates three independent, adjustable, constant frequency buck converters, a
