Hi,
My customer is looking for a buck supply that can take 8-19V in, and provide up to 5.2V @ 1.5amps. The tricky part is that the load is down 2.8 meters of 26AWG cabling (3 strands 26AWG for V+ going to the load and 3 strands of 26AWG on GND coming back from the load) and they want to compensate for cable drop. As the load increasing the buck has to regulate to a higher output voltage to compensate for voltage drop from the resistance of the cable. I have seen a couple post point to the following article showing how to to compensate for cable drop with an INA but I was hoping that this has been simulated before in TINA.

They are looking at the LM27341 buck converter but want to be able to simulate the circuit before putting it on their board. Is this possible? Is there a starting point that someone has done in the past?
Ultimately they are open to any TI buck and want a solution that is cheaper than the LT6110 device that expensive. Therefore if there is a recommendation for a different Buck other than the LM27341 that is better suited for this application, please let me know.
Thanks!
