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 LTM4605E is guaranteed to meet specifi cations from the 0°C
to 85°C operating temperature range. Specifi cations over the –40°C to
85°C operating temperature range are assured by design, characterization
and correlation with statistical process controls. The LTM4605I is
guaranteed over the –40°C to 85°C operating temperature range.

Note 3: The LTM4605 is tested in a feedback loop that servos V
specifi ed voltage and measures the resultant V
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% tested at wafer level only.
Note 6: Absolute Maximum Rating of –5V on SW1 and SW2 is under
transient condition only.
