INTEGRATED DIGITAL POL POWER-MANAGEMENT SYSTEM SIMPLIFIES DESIGN, CUTS COSTS

摘要

Thanks to an innovative architecture, this system enables 32 POL converters to communicate effectively under the guidance of a single system controller. Power systems are becoming more complex. To satisfy different circuit power-supply voltage and current needs, more and more point-of-load (POL) regulators and dc-dc converters are crowding pc boards-to the point where they're becoming unmanageable. The problem is threefold: the amount of pc-board space being absorbed, the number of external components required, and the lack of coordination between the horde of POL converters.
