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
reliabilty and lifetime.
Note 2: The LTC3564E is guaranteed to meet performance specifications
from 0
°C to 125°C junction temperature. Specifications over the –40°C to
125
°C operating junction termperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3564I is guaranteed over the full –40
°C to 125°C operating junction
temperature range. High junction temperatures degrade operating
lifetimes. Operating lifetime is derated at junction temperatures greater
than 125
°C.
Note 3: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula:
LTC3564ES5: TJ = TA + (PD)(215°C/W)
LTC3564EDCB: TJ = TA + (PD)(64°C/W)
Note 4: The LTC3564 is tested in a proprietary test mode.
Note 5: Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
Note 6: 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.
