TPSM63606: Current Sensing in Inverting Buck Boost Application

Part Number: TPSM63606


I am using TPSM63606E to generate a -3.5V from +12V input in inverting buck boost application. I am adding a sense resistor from the -3.5V supply towards my load to measure the load current. Understood that when high current flows, there is a voltage drop across the sense resistor so the load will see a maximum voltage drop of 60mV. In this case, if I connect -3.5V_LOAD to pin 2 of R95, can the switcher helps to compensate back the voltage drop across the sense resistor?
