LMR16006: Noise reduction

Paul Sigafus

Part Number: LMR16006

I'm having an FCC radiated and conducted noise issue. Can anyone give me tips on passing FCC? Also, I'm really interested if anyone has passed FCC with the LMR16006X (700Mhz) device.

Hi Paul,
Can you share your layout? The best way to reduce EMI is to reduce the area of the switch node trace. If it isnt already, you should place your inductor as close as possible to the IC to reduce EMI. Application notes AN-2155 (http://www.ti.com/lit/an/snva638a/snva638a.pdf) and AN-2162 (http://www.ti.com/lit/an/snva489c/snva489c.pdf) are also good reads to help you.

Regards,
-Orlando
