Description
General part information
PM6641 Series
The PM6641 is a monolithic voltage regulator module specifically designed to supply DDR2/3 memory and chipset in ultra-mobile PC and real estate constrained portable systems.
It integrates three independent, adjustable, constant frequency buck converters, a ±2 Apk low drop-out (LDO) linear regulator and a ±15 mA low noise buffered reference.
Each regulator provides basic UV and OV protections, programmable soft-start and current limit and active soft-end.
