This is the picture of our voltage sensor model using AMC1311 for the closed loop control of boost/buck converter.

The simulation is working fine but when it comes to the physical hardware implementation the output is not achieved.

Hi Venkatesh,

Without any additional information I cannot say where the issue may be.

Please refer to the EVM for an example implementation:https://www.ti.com/tool/AMC1311EVM

As well as this slide deck of collateral: https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1164993/faq-isolated-data-converter-collateral-overview

On the input side we are getting the voltage division properly, but on the output side we are getting a constant output of 2.5v. Sometimes the output voltage is getting decreased with increase in the input.

I have attached the simulation file which I've used to recreate using hardware.
