1. Current Waveform and Setting of Mixed Decay Mode
At constant current control, in current amplitude (pulsating current) Decay mode, a point from 0 to 3 can
be set using 2-bit parallel data.
NF is the point where the output current reaches the set current value. RNF is the timing for monitoring
the set current.
The smaller the MDT value, the smaller the current ripple (peak current value). Note that current decay
capability deteriorates.
