OUT
After the output current to the load reaches the current value specified by RNF, torque or other means, the
output current to the load will be fed back to the power supply fully in Fast Decay mode.
Since the predefined current level > output
current, current control mode is switched
from Charge mode → NF → Fast Decay
mode even in the next chopping cycle.
