How to selection switching frequency of DC-DC converter.
Lets say say i have to design buck conver for our application. Now in market there is wide frequency range of chip availble im market.
How to select operating frequency of my applications.

Higher frequency = smaller magnetics.

Higher frequencies can also mean greater switching losses.

Everything is a trade-off.
