Sensing for Parallel Operation
Use default local sensing to enhance power sharing between units, as the
impedance of the load lines will tend to correct for current imbalance. If
you use remote sensing at the load for better voltage regulation, one
supply always operates in current limit mode and supplies most of the
power.
