LM3481: LM3481 problem - DC/ DC Booster Converter

Part Number: LM3481

Hello all

There is a problem with using Lm 3841.If the problem is applied, the output load will be reduced by applying the output load after 25 V output & 2.5 A design.
I would like to keep the output current from 1.3 A to 1.5 A, but the output drops gradually due to a battery voltage drop of 8.4 volts.The output current will be 1 ampere when using several times.I want to solve this problem.

    Sorry this post is confusing. What do you mean by "if the problem is applied"? What is the problem that you apply to the circuit?

    As seen from the schematic, R36 also feeds into the FB pin, which means your Vout is not a fixed value. Is this what you want?
