3 / 24 page LTM4600 3 4600fc 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 LTM4600E is 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 LTM4600I is guaranteed over the –40°C to 85°C temperature range. Note 3: Test assumes current derating versus temperature. Note 4: Guaranteed by correlation.
