Analog Devices Inc. Silent Switcher® Solutions for EMI Compliance

Analog Devices Inc. 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.

The Silent Switcher architecture offers high efficiency at high switching frequencies ( >2MHz) with ultralow Electromagnetic Interference (EMI) emissions, offering very compact solutions while optimizing high efficiency at light load with ultra-low quiescent current. The Silent Switcher family uses special design and packaging techniques to offer 95% efficiency at 2MHz while easily passing the CISPR 25 Class 5 Peak EMI limits.

The Silent Switcher 2 Regulators’ design, exceptional EMI/EMC performance, and small overall solution size eliminate PCB layout sensitivity. The features of the Silent Switcher 2 Regulator series allow these devices to be used on any PCB, simplify product design, and reduce risks even when using two layer PC boards.
