CURRENT SHARE LOOP COMPENSATION
The crossover frequency of the current share loop should be at least one decade lower than that of the voltage loop
in order to eliminate the interaction between the two loops. A capacitor from SCOMP to ground is usually enough
for the share loop compensation. Choose the crossover frequency of current share loop (f
