Step-Down (Buck) Converter

Texas Instruments non-isolated step-down regulator products are part of TI's large switching regulator portfolio. Step-down DC/DC converters, also called buck converters, address size, efficiency, performance and cost constraints in today's point-of-load designs.

Use the parametric search, download datasheets or application notes, order samples and evaluation modules, and use TI's powerful, easy-to-use WEBENCH® design tools to get started today.
