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. Voltage on any pin may not exceed 6V.
Note 2: The LTC3549E is guaranteed to meet performance specications
from 0°C to 85°C. Specications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 3: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula:
LTC3549: TJ = TA + (PD)(64°C/W)
This IC includes overtemperature protection that is intended to protect the
device during momentary overload conditions. Overtemperature protection

ELECTRICAL CHARACTERISTICS
becomes active at a junction temperature greater than the maximum
operating junction temperature. Continuous operation above the specied
maximum operating junction temperature may impair device reliability.
Note 4: The LTC3549 is tested in a proprietary test mode that connects VFB
to the output of the error amplier.
Note 5: Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
Note 6: ΔVOVL is the amount VFB must exceed the regulated feedback
voltage.
Note 7: Determined by design, not production tested.
