All values shown reflect average measurements. These values are design targets and not characterization results.
If the FC option is selected, for time 1/(32 x f
level, the circuit is maintained in the high-current state to allow the load capacitors to charge quickly. Then the circuit
is returned to the low-current state until the next voltage level change occurs.
