Hi,

i am trying to implement Current sense voltage feedback loop using INA138 for inductor current but simulation results does NOT regulate the output voltage.

i have attached the simulation file, plz help me to reach the solutionCSA-MAIN-1 - autosave 19-06-19 11_40.TSC

I am not sure what your goal is?

Are you trying to control the inductor current or the output current?

Is this for some kind of battery charger?

What are your specifications?

Hi,

My goal is to implement CV/CC closed loop control by measuring INDUCTOR current (LM25011 has diode current measurement inbuilt), for regulating o/p voltage.

Plz help

I am not sure that is the best way to build CV/CC. You may want to look at the LM5117 or LM25117.

Also, check the TI website for application notes that might help.
