Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Includes leading edge blanking delay, R
production.
Note 3: FB is driven by a servo loop amplifier to control V
tests.
Note 4: Set FB to –0.3V, 2.5V and insure that COMP does not phase invert.
Note 5: The LTC3723E–1/LTC3723E-2 are guaranteed to meet

performance specifications from 0°C to 70°C. Specifications over the
–40°C to 85°C operating temperature range are assured by design,
characterization and correlation with statistical process controls.
Note 6: This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125°C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
