LM5170: 12V error amplifier: bandwidth requirements

Part Number: LM5170
Other Parts Discussed in Thread: LM6142, TLV271,


the datasheet shows the outer voltage loop on page 48:

What are the requirements for the 12V error amplifier?

My customer is using a TLV271 with 3MHz bandwidth. Our EVM has an LM6142 with 17MHz BW.
Is the TLV271 too low in BW?
