Switched-mode power supplies (SMPS) serve as the foundation of contemporary electronics — efficient, compact, and vital in applications ranging from mobile devices to industrial automation. At the core of every SMPS is a key component — the transformer. Traditionally, wound-core transformers have been the norm, but as the demand for miniaturization, thermal efficiency, and high-frequency operation grows, planar transformers are emerging as a significant alternative. This blog examines whether planar transformers represent the future of SMPS design by evaluating their structure, performance, benefits, and drawbacks in comparison to conventional transformers.
