The new page introduces various reference materials and electronic components that can be used to achieve low EMI by utilizing Analog Devices' synchronous buck regulators and Coilcraft's power inductors.

Analog Devices' Silent Switcher 2 LT8640S, LT8643S, and LT8650S, which minimize EMI emissions, combine bypass capacitors, ground planes, copper fills, and other components that optimize fast current loops to provide high efficiency at high switching frequencies. Operating as a 42V, 6A regulator with a quiescent current of 2.5µA and maximum efficiency of 96% at 1MHz, they provide fast, clean, and low overshoot switching edges, delivering high-efficiency operation and buck ratios even at high switching frequencies.

When Coilcraft's power inductors are used together with the LT8640S, LT8643S, and LT8650S, EMI is reduced even in harsh and noisy environments. Coilcraft's XFL5030 series shielded power inductors have a DC resistance of 2.15 milliohms. With maximum current handling capability of 11.5A, smooth saturation, and composite construction that minimizes audible noise, the XFL5030 is a device well-suited for high-frequency applications.

Coilcraft's XEL6030 series high-current shielded power inductors provide low DC resistance and AC losses in the 2~5MHz high-frequency band. With smooth saturation current and excellent current handling capability, they have immunity to high-current spikes, and the inductance range is 0.15~3.3µH. Devices in both the XFL5030 and XEL6030 series comply with AEC-Q200 Grade 1 automotive specifications and RoHS standards, and are manufactured using halogen-free materials.

Mouser has published a whitepaper titled "How to Dial Down the Noise: Limiting EMI," which is available for free download, to provide a detailed technical explanation of solutions for limiting EMI. Paul Golata, Mouser's senior technical content specialist, explains how to develop low-EMI solutions required in today's demanding applications by using products from Analog Devices and Coilcraft together.
