Coupled inductor for multiphase buck converters

Postby williamhawk » 17 Oct 2017, 09:35

I found some applications note that using coupled inductor in multiphase buck converters can help in both efficiency and transient response. It seems like it is good enough to replace the conventional inductors in this application.

However, there are many people still use conventional inductors. Are there any shortcomings of using coupled inductor in the performance wise (in additional to the cost)?

Please help.
Thanks!

I didn't find the right solution from the Internet.
