Note 1:
Stresses beyond those listed under Absolute Maximum Ratings factors. TJ is calculated from the ambient temperature TA and power may cause permanent damage to the device. Exposure to any Absolute dissipation PD according to the following formula: Maximum Rating condition for extended periods may affect device TJ = TA + (PD • 150°C/W) reliability and lifetime.
Note 3:
Specification is guaranteed by design and not 100% tested in
Note 2:
The LTC3525 is tested under pulsed load conditions such that production. TJ ≈ TA. The LTC3525E is guaranteed to meet performance specifications
Note 4:
Current Measurements are performed when the LTC3525 is not from 0°C to 85°C. Specifications over the –40°C to 85°C operating switching. junction temperature range are assured by design, characterization and correlation with statistical process controls. The LTC3525I is guaranteed
Note 5:
This IC includes overtemperature protection that is intended over the –40°C to 125°C operating junction temperature range. Note that to protect the device during momentary overload conditions. Junction the maximum ambient temperature consistent with these specifications temperature will exceed 125°C when overtemperature protection is active. is determined by specific operating conditions in conjunction with board Continuous operation above the specified maximum operating junction layout, the rated package thermal impedance and other environmental temperature may impair device reliability.
