Hi Feng, I have gone through with LM5170/71 Or PMP21943 but we have not got 96V 60A solutions in these document. Could you please share exact document/ reference in which it is used 96V with external gate driver and etc with 60A. Note: We have PMP21943 doc…
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,
