August 10, 2021 Blog Automotive application circuits must meet strict EMI standards to avoid interfering with broadcast and mobile service frequency bands. In this article we look specifically at two possible solutions for a 4-switch buck-boost controller and compare EMI chamber results. A 4-switch buck-boost combines a buck and boost controller into a single IC, where the converter operates as a buck when the output is lower than the input, and as a boost when the output is higher than the input.
