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 3: Guaranteed by design, not directly tested.
Note 4: Current ?ows out of pin.
Note 5: Current limit guaranteed by design and/or correlation to static test.
Slope compensation reduces current limit at higher duty cycle.
Note 2: The LT3487E is guaranteed to meet speci?ed performance from
0°C to 85°C. Speci?cations over the –40°C to 85°C operating range are
assured by design, characterization and correlation with statistical process
controls.
