Note 4: Specifications are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by

design and characterization.

Note 5: The device supports a peak output current of 1A. Continuous operation with 1A output current at elevated temperature is not

guaranteed. With sustained high current (> 100ms, > 1A), the junction temperature (TJ) rises to the thermal shutdown thresh-

old. The stated Minimum Continuous Output Current values represent what the typical operating circuit can achieve when

considering device and component variations. See the Output Current section for more information.

Note 6: 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.
