The
● denotes the specications which apply over the full operating junction
temperature range, otherwise specications are at TA = 25°C. VCC = 13V, RSET = 80k, no load on any outputs, unless otherwise noted.
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 LT3782AE is guaranteed to meet performance specications
from 0°C to 85°C. Specications over the –40°C to 125°C operating
junction temperature range are assured by design, characterization and
correlation with statistical process controls. The LT3782AI is guaranteed
to meet performance specications over the full –40°C to 125°C operating
junction temperature range.
Note 3: 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.
