PowerWise® Synchronous Buck Regulators
National Semiconductor's full-featured PowerWise synchronous buck regulators provide high efficiency synchronous DC-DC step-down power conversion for point-of-load (PoL) applications. Products offer a full range of features and options enabling designers to fully customize their power solution to meet system needs. When powering multiple points-of-load, a combination of appropriate devices can be chosen based upon the features to create a small, efficient, and complete solution with minimal external components or circuitry.
