ISOW1412: What is Switching Freq for Isolated Power Supply ?

Hi Karan,

Thank you for reaching out.

The switching frequency of the internal DC/DC converter is 25MHz. The best way to filter the switching noise is to use ferrite beads (FB) on both supply pins as suggested in ISOW1412 datasheet. You can also refer to the below tech note on ISOW7741 that describes various design guidelines optimize the design for low emissions. These guidelines are equally applicable for ISOW1412 as well. Thanks.
