Note 3: When the inductor is in continuous conduction, the output voltage has a DC regulation level lower than the error-comparator
threshold by 50% of the ripple. In discontinuous conduction, the output voltage has a DC regulation level higher than the
error-comparator threshold by 50% of the ripple. The core SMPSs have an integrator that corrects for this error. The NB
SMPS has an offset determined by the ILIM3 pin, and a -6.5mV/A load line.
Note 4: Production testing limitations due to package handling require relaxed maximum on-resistance specifications for the TQFN
package.
Note 5: Specifications to T A = -40 ° C to +105 ° C are guaranteed by design, not production tested.
