Hi Dilip,

Most buck converters can be operated as IBB with a few caveats. When using a buck step down regulator as an IBB application, I would consider checking to see if the absolute max voltage and peak current ratings of the part can withstand the IBB operation.

I've linked some resources that will help guide your design for IBB with those parameters.
