ELECTRICAL CHARACTERISTICS

TYPICAL PERFORMANCE CHARACTERISTICS

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 LTC3526E-2 is guaranteed to meet performance specifications

from 0°C to 85°C. Specifications over –40°C to 85°C operating

temperature range are assured by design, characterization and correlation

with statistical process controls.

Note 3: Specification 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°C when overtemperature protection is active.

Continuous operation above the specified 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

60°C/W.
