Abstract

Synchronous buck converters are known to cause broadband EMI typically in 30-300 MHz range. This paper treats the broadband EMI problem by analyzing the root cause, and coupling paths, and it proposes valuable broadband noise mitigation techniques that can be applied before, during, or after the development cycle allowing designers to design the synchronous buck converter with optimal EMC performance. The noise mitigation techniques suggested in this paper divides into three parts: Mitigations techniques that apply at the source level, coupling path level, and direct radiation level.
