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 LTC3412E is guaranteed to meet performance specifications
from 0°C to 85°C. Specifications over the – 40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls. The LTC3412I is guaranteed to meet
specified performance over the – 40°C to 85°C temperature range.
Note 3: The LTC3412 is tested in a feedback loop that adjusts VFB to
achieve a specified error amplifier output voltage (ITH).
Note 4: Dynamic supply current is higher due to the internal gate charge
being delivered at the switching frequency.
Note 5: TJ is calculated from the ambient temperature TA and power
dissipation as follows: LTC3412: TJ = TA + PD (37.6°C/W).
Note 6: 4MHz operation is guaranteed by design and not production tested.
Note 7: Switch on resistance is guaranteed by design and test correlation
in the UF package and by production test in the FE package.
