Hi Shankar,
Please create a new thread for requirement 1, you may start the new thread with UCC2897A.
For requirement 2, you can use LM5170. You need to use external gate drivers as 96V is too high. Please refer to PMP21943.
You may also consider LM5171…
Part Number: LM5170-Q1 Other Parts Discussed in Thread: PMP21943 , LM5170 , PMP Dear engineers:
We apply the LM5170 to reverse polarity buck-boost and some problems occurred, the reference design is PMP21943 from TI official website. Problem1: The inductor…
Hi Feng Ji,
i want to make modification to the demo board : https://www.ti.com/tool/PMP21943 .
the goal is to implement
Input voltage 40VDC t0 250VDC.
Output voltage 31VDC.
Output power 1500watt.
PLS advise.
Thank You

Hi Aiwen,
thank you for using the E2E forum.
When targeting in output power of 1kW you need to go with a multiphase design.
Below reference designs might be a good starting point:

Hello Cherry,
The TL431 might work with an optocoupler at 300kHz to 1MHz but it would require a very aggressive compensation network to maximize the TL431's bandwidth. If the TL431's bandwidth is not sufficient, a better solution would be to use a discrete…
Hi Satoshi-san,
Thank you for reaching out. 1kW looks excessive for a dual phase LM5122 or LM5122ZA. You may refer to
Please let us know if you would like to proceed this approach.
Thanks,
