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

reliability and lifetime.

Note 2: The LTC3313E is guaranteed to meet performance specifications

from 0°C to 125°C junction temperature. Specifications over the –40°C

to 125°C operating junction temperature range are assured by design,

characterization, and correlation with statistical process controls. The

LTC3313J is guaranteed over the –40°C to 150°C operating junction

temperature range.

The l denotes the specifications which apply over the specified operating

temperature range, otherwise specifications are at TA = 25°C (Notes 2, 3). VIN = 3.3V, VEN = VIN, MODE/SYNC = 0V, unless otherwise noted.

Note 3: The LTC3313 includes overtemperature protection which protects

the device during momentary overload conditions. Junction temperatures

will exceed 150°C when overtemperature protection is active. Continuous

operation above the specified maximum operating junction temperature

may impair device reliability.

Note 4: Supply current specification does not include switching currents.

Actual supply currents will be higher.

Note 5: Inductor ripple current equal to 30% of full load (4.5AP-P).
