Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
This IC includes overtemperature protection that is intended may cause permanent damage to the device. Exposure to any Absolute to protect the device during momentary overload conditions. Maximum Rating condition for extended periods may affect device Overtemperature protection is active when junction temperature exceeds reliability and lifetime. the maximum operating junction temperature. Continuous operation above
Note 2:
The LTC3562E is guaranteed to meet performance specifi cations the specifi ed maximum operating junction temperature may result in from 0°C to 85°C. Specifi cations over the –40°C to 85°C operating device degradation or failure. temperature range are assured by design, characterization and correlation
Note 4:
The serial port is tested at rated operating frequency. Timing with statistical process control. parameters are tested and/or guaranteed by design. 3562fa 4
