Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC3413E is guaranteed to meet performance specifications
from 0 C to 70 C. Specifications over the –40 C to 85 C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 3: The LTC3413E is tested in a feedback loop that adjusts V

Note 4: Dynamic supply current is higher due to the internal gate charge
being delivered at the switching frequency.

Note 6: 2MHz operation is guaranteed by design and not production tested.
Note 7: Shutdown current and SW leakage current are only tested during
wafer sort.
Note 8: This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125 C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
