Comparing inductor-less, inductor-based switching regulators

Posted: 13 Aug 2009     Print Version  Bookmark and Share

Keywords:switching regulators  inductor  inductorless 

Inductor-based switching regulators (SRs) have historically represented the preferred architecture for power supplies. Nowadays, for low-power and highly integrated electronic systems, embedded inductor-based SRs show several limitations that can be overcome by the use of inductorless SR architectures. This article provides a qualitative and quantitative comparison between both types of SR in terms of implementation cost (BOM and pin count) and performance (efficiency, noise and reliability).
