Would you give more detail about the sense pin? What do you mean "not correct"? The voltage is too high or too low ... What resistor value to you put on Sense pin? would you send a waveform here to show the issue?
Where do you put the resistor load? Do you put the resistor load between OUT1 and OUT2? We have to make sure the load current go through the sense resistor.
Resister load is OK if the peak Sense pin voltage is below 500mV. Would you use a waveform to show sense pin voltage and OUTx voltage?
