Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
Current measurements are made when the output is not switching. may cause permanent damage to the device. Exposure to any Absolute
Note 5:
This IC includes overtemperature protection that is intended Maximum Rating condition for extended periods may affect device to protect the device during momentary overload conditions. Junction reliability and lifetime. temperature will exceed 125°C when overtemperature protection is active.
Note 2:
The LTC3537 is guaranteed to meet performance specifi cations Continuous operation above the specifi ed maximum operating junction from 0°C to 85°C. Specifi cations over the –40°C to 85°C operating temperature may result in device degradation or failure. temperature range are assured by design, characterization and correlation
Note 6:
Failure to solder the exposed backside of the package to the PC with statistical process controls. board ground plane will result in a thermal resistance much higher than
Note 3:
Specifi cation is guaranteed by design and not 100% tested in 68°C/W. production. 3537fd 4
