Abstract

Inductor-based Switching Regulators (SR) 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 paper provides a qualitative and quantitative comparison between both types of SR in terms of implementation cost (Bill of Material, and pin count), and performance (efficiency, noise, and reliability)...
