Abstract

Switching operations of the DC-DC converter is the major source of electromagnetic emission (EMI) of power management circuits. In this paper, a design guideline for inductive snubber circuit is developed to reduce EMI of DC-DC converter. A switching loop of the DC-DC converter is modeled and ringing noise on the switching node is analyzed. Circuit schematic simulation is performed to verify the effectiveness of the EMI suppression and to optimize the suppression effect.
