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: Based on long term current density limitations.

Note 3: The LTC3220E/LTC3220E-1 are 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 LTC3220I/LTC3220I-1

are guaranteed to meet performance specifications over the full –40°C to

125°C operating temperature range.

Note 4: These devices include overtemperature protection that is intended

to protect the devices during momentary overload conditions. Junction

temperatures will exceed 125°C when overtemperature protection is

active. Continuous operation above the specified maximum operating

junction temperature may result in device degradation or failure.

Note 7: Guaranteed by design.
