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 LTC3417AE-1 is guaranteed to meet specified performance

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

ambient temperature range are assured by design, characterization

and correlation with statistical process controls. The LTC3417AI-1 is

guaranteed to meet performance specifications over the –40°C to 125°C

operating temperature range.

Note 4: Total supply current is higher due to the internal gate charge being

delivered at the switching frequency.

Note 5: Switch on-resistance is guaranteed by design and test correlation

on the DHC package and by final test correlation on the FE package.

Note 6: Variable frequency operation with resistor is guaranteed by design

but not production tested and is subject to duty cycle limitations.

Note 7: 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.
