Note 1:
Stresses beyond those listed under Absolute Maximum Ratings is guaranteed over the –40°C to 85°C temperature range. The may cause permanent damage to the device. Exposure to any Absolute LTM46000HVMP is guaranteed and tested over the –55°C to 125°C Maximum Rating condition for extended periods may affect device temperature range. reliability and lifetime.
Note 3:
For output current derating at high temperature, please refer to
Note 2:
The LTM4600HVE is guaranteed to meet performance Thermal Considerations and Output Current Derating discussion. specifications from 0°C to 85°C. Specifications over the –40°C to 85°C
Note 4:
Test assumes current derating versus temperature. operating temperature range are assured by design, characterization
Note 5:
Guaranteed by correlation. and correlation with statistical process controls.
