range, otherwise specifications are at TA = 25°C. VIN = 15V, VC = 0.8V, SHDN, SYNC and switch open 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 LT1961E is guaranteed to meet performance specifications
from 0
°C to 125°C junction temperature. Specifications over the –40°C to
125
°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LT1961I is guaranteed over the – 40C to 125C operating junction
temperature range.
Note 3: Minimum input voltage is defined as the voltage where the
internal regulator enters lockout. Actual minimum input voltage to
maintain a regulated output will depend on output voltage and load
current. See Applications Information.
