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 LTC3616E is guaranteed to meet performance specifications
over the 0°C to 85°C operating junction temperature range. Specifications
over the –40°C to 125°C operating junction temperature range are
assured by design, characterization and correlation with statistical process
controls. The LTC3616I is guaranteed to meet specifications over the
full –40°C to 125°C operating junction temperature range. Note that
the maximum ambient temperature is determined by specific operating
conditions in conjunction with board layout, the rated package thermal
resistance and other environmental factors.
Note 3: This parameter is tested in a feedback loop which servos VFB to
the midpoint for the error amplifier (VITH = 0.75V).
Note 4: External compensation on ITH pin.

l
denotes the specifications which apply over the full operating junction
temperature range, otherwise specifications are at TJ = 25°C. VIN = 3.3V, RT/SYNC = SVIN unless otherwise specified (Notes 1, 2, 11).

Note 5: Tying the ITH pin to SVIN enables the internal compensation and
AVP mode.
Note 6: Dynamic supply current is higher due to the internal gate charge
being delivered at the switching frequency.
Note 7: See description of the TRACK/SS pin in the Pin Functions section.
Note 8: In sourcing mode the average output current is flowing out of SW
pin. In sinking mode the average output current is flowing into the SW Pin.
Note 9: See description of the MODE pin in the Pin Functions section.
Note 10: Guaranteed by correlation and design to wafer level
measurements for QFN packages.
Note 11: 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.
