Note 1: Absolute Maximum Ratings are those values beyond which the
MTBF of a device may be impaired.
Note 2: Based on long-term current density limitations. Assumes an
operating duty cycle of ≤10% under absolute maximum conditions for
durations less than 10 seconds. Max charge pump current for continuous
operation is 500mA.
Note 3: Based on long-term current density limitations.
Note 4: The LTC3208E is guaranteed to meet performance speci?cations
from 0°C to 70°C. Speci?cations over the –40°C to 85°C ambient
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 5: 1.5x mode output impedance is de?ned as (1.5V BAT – V CPO )/I OUT .
2x mode output impedance is de?ned as (2V BAT – V CPO )/I OUT .
Note 6: All values are referenced to V IH and V IL levels.
Note 7: Guaranteed by Design.
