Note 3: Specifications are 100% production tested at T A = +25 ° C. Limits over the operating temperature range are guaranteed by
design and characterization.
Note 4: Continuous operation with 1A at elevated ambient temperature and low voltage is not guaranteed. Under worst-case con-
ditions, die thermal protection cannot be activated after 100ms of 1A load application. See the continuous output current
parameter for a conservative estimate of current that can be maintained at T A = +85 ° C.
Note 5: Switching frequency decreases if input voltage is > 83% of the output voltage selected. This allows duty factor to drop to
values necessary to boost output voltage less than 25% without the use of pulse widths less than 60ns.
Note 6: Contact factory for other options.
Note 7: The output voltage regulation is a direct function of the peak current in the nMOS power switch. The inductor current (I LX )
described in the conditions of the steady-state output voltage specification corresponds to the peak inductor current.
Note 8: Once ATM threshold is reached boost switching stops in 1μs (typ), but the transition to ATM does not occur until V OUT has
fallen equal to V IN .
