2. Changing the Predefined Current to the Lower Value
During deceleration, the regulator enters fast-decay mode immediately after the end of the current decay
slope of slow-decay mode. The distortion of the current waveform can be reduced by the regenerative current
from a coil that flows back to the power supply. Two CK cycles later, the regulator exits fast decay mode and
enters Charge mode. (The fast-decay time, which is specified herein as two CK cycles, varies depending on
the mode setting. A detailed description of the mode setting is provided in the Current Decay Mode section.)
When VRF reaches the reference voltage (Vref), the regulator enters Discharge mode. Four CK cycles later,
the regulator exits Discharge mode and enters Charge mode. If VRF > Vref when it enters Charge mode,
however, it then reenters Discharge mode. Four CK cycles later, VRF is again compared against Vref. If
VRF < Vref, the regulator remains in Charge mode until VRF reaches Vref.
