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 LT1933E is guaranteed to meet performance speci?cations
from 0°C to 70°C. Speci?cations over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
guaranteed over the –40°C to 125°C temperature range. The LT1933H
speci?cations are guaranteed over the –40°C to 150°C temperature range.
Note 3: Current limit guaranteed by design and/or correlation to static test.
Slope compensation reduces current limit at higher duty cycle.
Note 4: Current ?ows out of pin.
Note 5: Current ?ows into pin.
with statistical process controls. The LT1933I speci?cations are
