Bringing Isolation, High Efficiency, and Lower Noise to Switching Power Supplies (Download)

Read this article online.

Power designers in search of high power efficiency in step-up and step-down conversion with switching power supplies need to minimize DC-DC power converter EMI noise. This article will provide some unique EMI noise mitigation solutions.

Isolated DC-DC bias converters provide isolated communication and sensing via bias power across the isolation barrier. Current/voltage sensors, gate drivers, and digital isolators usually require power that can range from less than 15 W to as little as tens of milliwatts.
