Other Parts Discussed in Thread: TPS54061, LMR36503-Q1

I am designing a dc-dc converter for supercapacitor charger of value 20F 6V. Its takes the input from 12V battery. The design use the TPS54061-Q1 part having current limit feature.

I want to know whether it is a right choice or not?

Is any problem at the time of starting?

Yes, TPS54061 seems like a good fit. One key thing is it operates with a cycle by cycle current limit, not hiccup.

Also, LMR36503-Q1 could be considered, though, its internal compensation is integrated which could negatively impact the dynamic behavior of the device, potentially.
