ELECTRICAL CHARACTERISTICS (continued)
(V
noted.) (Note 5)
Note 1: IN input voltage must not drop below minimum voltage because of ripple or transient conditions.
Note 2: Guaranteed by design.
Note 3: Boost frequency is 2x step-down frequency.
Note 4: For proper startup, EN must exceed V
Note 5: Specifications to -40°C are guaranteed by design but not production tested.
