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 LTM4622A is tested under pulsed load conditions such that
T
J
≈ T
A
. The LTM4622AE is guaranteed to meet performance
specifications over the 0°C to 125°C internal operating temperature
range. Specifications over the full –40°C to 125°C internal operating
temperature range are assured by design, characterization and correlation
with statistical process controls. The LTM4622AI is guaranteed to meet
specifications over the full –40°C to 125°C internal operating temperature
range. Note that the maximum ambient temperature consistent with
these specifications is determined by specific operating conditions in
conjunction with board layout, the rated package thermal resistance and
other environmental factors.

Note 4:
100% tested at wafer level.
Note 5:
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.
