Note 2: When the inductor is in continuous conduction, the output voltage will have a DC regulation level lower than the error-com-
Note 3: Default setting for the MAX8716.
Note 4: Specifications are guaranteed by design, not production tested.
Note 5: Production testing limitations due to package handling require relaxed maximum on-resistance specifications for the thin QFN
Note 6: Specifications from 0°C to -40°C are guaranteed by design, not production tested.
