VIN, VOUT Voltage ........................................ –0.3V to 6V
SW Voltage ................................................. –0.3V to 6V
SW Voltage < 100ns ................................... –0.3V to 7V
SHDN Voltage ............................................. –0.3V to 6V
Operating Temperature Range
(Notes 2, 5).......................................... –40°C to 85°C
Storage Temperature Range................... –65°C to 125°C
Lead Temperature (Soldering, 10 sec) .................. 300°C
(Note 1)
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 LTC3525DE 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: Specication is guaranteed by design and not 100% tested in
production.

Note 4: Current Measurements are performed when the LTC3525D is not
switching.
Note 5: 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 specied maximum operating junction
temperature may impair device reliability.
Note 6: Consult LTC Marketing for other output voltage options.
