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 LTM4607E is guaranteed to meet specifications from 0°C to
85°C operating temperature range. Specifications over the –40°C to 85°C
operating temperature range are assured by design, characterization and
correlation with statistical process controls. The LTM4607I is guaranteed
over the –40°C to 85°C operating temperature range.
Note 3: The LTM4607 is tested in a feedback loop that servos V COMP to a
specified voltage and measures the resultant V FB .
Note 4: Turn-on and turn-off time are measured using 10% and 90%
levels. Transition delay time is measured using 50% levels.
Note 5: 100% test at wafer level only.
Note 6: Absolute Maximum Rating of –5V on SW1 and SW2 is under
transient condition only.
