Part Number: UCC2897A
Other Parts Discussed in Thread: PMP20878

Hi Team

My customer designed circuit for PoE isolated active clamp use UCC2897A and TPS2373-4.

They did reference PMP20878.

They asked to confirm that there is no problem with the value for the compensation circuit.

As a Confidential issue, circuits can not be shared with the portal.

I want to contact by email.

Hello Charles,

Thank you for your interest in UCC2897A.
If their input and output power range is the same as PMP20878, then they can use the same values for the compensation loop. The loop stability of PMP20878 is listed in the design guide attached.
www.ti.com/.../tidudb0.pdf
They can also use the Power stage designer tool to review their loop design.

Please share the business opportunity for this design, like production start date, volume, application etc

Regards,
Sonal

Hi Sonal

Customer's circuit only reference to PMP20878, but the overall specifications are different.
I don't know the feedback value using 'Power stage designer'.
My customer think important confidential about their circuit.
So, I want to contact by email.
