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,
