Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
The LTM8063 contains overtemperature protection that is may cause permanent damage to the device. Exposure to any Absolute intended to protect the device during momentary overload conditions. The Maximum Rating condition for extended periods may affect device internal temperature exceeds the maximum operating junction temperature reliability and lifetime. when the overtemperature protection is active. Continuous operation
Note 2:
Unless otherwise noted, the absolute minimum voltage is zero. above the specified maximum operating junction temperature may impair
Note 3:
The LTM8063E is guaranteed to meet performance specifications device reliability. from 0°C to 125°C internal. Specifications over the full –40°C to
Note 5:
PG transitions from low to high. 125°C internal operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM8063I is guaranteed to meet specifications over the full –40°C to 125°C internal operating temperature range. Note that the maximum internal temperature is determined by specific operating conditions in conjunction with board layout, the rated package thermal resistance and other environmental factors.
