ELECTRICAL CHARACTERISTICS

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The LTC3406AE is guaranteed to meet performance specifications

from 0°C to 85°C. Specifications over the –40°C to 85°C operating

temperature range are assured by design, characterization and correlation

with statistical process controls. The LTC3406AI is guaranteed to meet the

specified performance over the full –40°C to 125°C operating temperature

range.

Note 4: The LTC3406A is tested in a proprietary test mode that connects

Note 5: Dynamic supply current is higher due to the gate charge being

delivered at the switching frequency.

Note 6: 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.

Note 7: Limited by long term current density considerations.
