Constant-Current Regulation
When the Vref voltage is kept constant, the constant current regulator keeps the output current constant by
using a peak current detection technique.
(1)
Constant-current chopping
When VRS reaches the reference voltage (Vref), the regulator enters Discharge mode.
After four cycles of CK, an internal clock generated by OSC, the regulator moves from Discharge mode
to Charge mode.
(2)
Changing the predefined current (during deceleration)
When VRS reaches the reference voltage (Vref/6), the regulator enters Discharge mode. Four CK cycles
later, the regulator exits Discharge mode and enters Charge mode. If VRS > Vref/6 when it enters
Charge mode, however, it then reenters Discharge mode. Four CK cycles later, VRS is again compared
against Vref/6. If VRS < Vref/6, the regulator enters and remains in Charge mode until VRS reaches
Vref/6.
