ELECTRICAL 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

reliabilty and lifetime.

Note 2: The LTC3564E is guaranteed to meet performance specifications

from 0

°C to 125°C junction temperature. Specifications over the –40°C to

125

°C operating junction termperature range are assured by design,

characterization and correlation with statistical process controls. The

LTC3564I is guaranteed over the full –40

°C to 125°C operating junction

temperature range. High junction temperatures degrade operating

lifetimes. Operating lifetime is derated at junction temperatures greater

than 125

°C.

Note 4: The LTC3564 is tested in a proprietary test mode.

Note 5: Dynamic supply current is higher due to the gate charge being

delivered at the switching frequency.

Note 6: 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 impair device reliability.
