Silent Switcher® Solutions for EMI Compliance

Analog Devices Electromagnetic Interference (EMI) compliance is often mandatory and a critical design challenge for medical, automotive, test, and measurement equipment manufacturers. For example, if a device fails EMI compliance, it not only creates a long design cycle, it also increases cost as a result of re-design and re-evaluation for EMI compliance. To overcome these challenges, Analog Devices offers Silent Switcher® Architecture which minimizes the risk of problems caused by EMI, making µModule® Regulators and Discrete DC-DC ideal for noise-sensitive applications.
