LM63635-Q1: EMI spec

Roy Chou1

Part Number: LM63635-Q1
Other Parts Discussed in Thread: LM63625EVM

Team,

We use LM63635-Q1 to achieve Vin = 26V, Vout = 12V, Iout = 2.5A. Could you let me know whether this part could pass below EMI test? Is it easy to pass if we follow the layout?

Hello

Unfortunately, it is always tricky to pass an EMI specification.

Your input voltage is 26V, so you will get more radiated EMI than at a lower input, but your

conducted EMI should be about the same as shown in the data sheet.

My best advice would be to purchase the LM63625EVM (for TSSOP) and test it under your

application conditions.

Then if that works for you, you can copy the EVM layout and the EMI filer.

Thanks
