CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are
at the specified temperature and are pulsed tests, therefore: T J = T C = T A
Electrical Specifications
V DD = V IN = V EN = 3.3V, C1 = C2 = 10μF, L = 1.8μH, V O = 1.8V (as shown in Typical Application Diagram),
unless otherwise specified.
