Help for buck circuit design

[somedisatance]

HI：

I want to design a circuit for my product

Input voltage required：≤150~200V

Output voltage：36V

output power：≥100W

Service temperature：150℃

Are there any recommended designs that can be used？

Thanks

@somedisatance ,

Service temperature：150℃  -->what is the service temperature?

My understanding is ambient tempertautre, If yes, then since most of the driver ICs maximum operating temperature is upto 150℃, when operating there's some loss on the IC, so no possible to work with 150℃ ambient temerature.

You understand correctly, but this is only one indicator. Generally, devices with a nominal temperature of 150 ℃ can be used. Is there a recommended circuit or IC?

@somedisatance ,

I have checked in our product lines, no suitable recommendations as the 150 ℃ is required.
