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
specifi cations from 0°C to 85°C. Specifi cations 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 specifi cations 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 specifi ed maximum operating
junction temperature may result in device degradation or failure.
Note 5: 1.5x mode output impedance is defi ned as (1.5V
2x mode output impedance is defi ned as (2V
Note 6: All values are referenced to V
