Other Parts Discussed in Thread: PMP8606
I am designing a 3kW power supply with dual output voltage (+-125V) using UCC28950 for the dc-dc stage, and I'd appreciate if you answer my questions.
According to TI Switch-mode power converter compensation made easy, I am trying to implement a peak current mode control with a type II compensator.
What considerations are required for a dual output voltage power supply compared to a single output voltage one? Is there any TI reference designs with dual output voltage so that I can get some idea how I should close the feedback loop?
Also, could you advise if the compensation network has to be isolated for this application?
It seems to me that PMP8606 is the only reference design for UCC28950 with an optocoupler feedback. Is there any other UCC28950 reference designs with an optocoupler feedback?
Thank you very much,
