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.
