Description
The STEVAL-ISA050V1 demonstration board is based on the PM6641, that is a monolithic voltage regulator module, with internal Power MOSFET, specifically designed to supply DDR2/3 memory and chipset in ultra-mobile PC and real estate 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 is provided of basic under voltage (UV) and over voltage (OV) protections, programmable soft-start and current limit, active soft-end and pulse-skipping at light loads.
