hi,
I want to set the input voltage between 22-30V and the output voltage to 28.5V. However, I am unable to limit the input voltage through the IC. I can set the output voltage to 28.5V, 10A.
How can I limit the input voltage?

Thank you for using E2E forums, I am not sure what you mean by limiting the input voltage? Normally you set the input voltage with the power supply, the IC does not play a role in that. Could you please elaborate your question?

I aim to limit the input voltage to the range of 22V-30V and ensure that it stays within this voltage range. Additionally, I intend to fix the output voltage at 28.5V. Consequently, I want the duty cycle to be in the range of 20%-90%
Hi,
I am really not sure if we have both the same understanding.
Input voltage = is the input voltage to the SMPS (Switch Mode Power supply) in this case the LM5175
Output voltage = Is the voltage generated and regulated by the SMPS
So the input voltage is coming from the outside the and the source of that supply needs to ensure that the voltage stays within a defined range.
The SMPS does not have in influence on that beside it would work in reverse operation.
So can you please clarify based on the above definitions what your requirements would be.
Best regards,
Stefan
Hi,
Sorry, I really do not understand your request.
Can you provide more details, maybe add a short drawing or schematic?
Best regards,
Stefan
