external parts with PTN78060A

Other Parts Discussed in Thread: PTN78060A

the three 4.7 uF capacitors C2 that are labeled 'Required' with the PTN - these are a little hard to get right now, and I'm wondering if I can use electrolytic capacitors in their place. we need to get our project moving forward fast, and I'm wondering if they have to be ceramic and why, if so. also, does TI sell these kind of parts at all, i.e. external parts required with a TI part?

thanks

the capacitors are available alright and I've already ordered them, but they will take time to come this time of year. this is why I was asking about using electrolytic capacitors in their place temporarily, and whether the ceramic ones are absolutely essential.

The ceramic capacitors are required for stability of the input bus and reduced input ripple on the PTN78060A buck Boost regulator.
