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. Pins of regulators should not exceed 6V

Note 2: The LTC3407E-4 is guaranteed to meet specified performance

from 0

°C to 85°C. Specifications over the –40°C and 85°C operating

temperature range are assured by design, characterization and correlation

with statistical process controls.

Note 3: The LTC3407-4 is tested in a proprietary test mode that connects

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

being delivered at the switching frequency.

Note 6: The DFN switch on-resistance is guaranteed by correlation to

wafer level measurements.
