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 LTC3537 is guaranteed to meet performance speci cations
from 0癈 to 85癈. Speci cations over the 40癈 to 85癈 operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 3: Speci cation is guaranteed by design and not 100% tested in
production.

Note 4: Current measurements are made when the output is not switching.
Note 5: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 125癈 when overtemperature protection is active.
Continuous operation above the speci ed maximum operating junction
temperature may result in device degradation or failure.
Note 6: Failure to solder the exposed backside of the package to the PC
board ground plane will result in a thermal resistance much higher than
68癈/W.
