ELECTRICAL CHARACTERISTICS
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 LTC3112 is tested under pulsed load conditions such that
TJ ≈TA. The LTC3112E is guaranteed to meet specications from
0°C to 85°C junction temperature. Specications over the –40°C to
125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3112I is guaranteed to meet specications from –40°C to 125°C
junction temperature. Note that the maximum ambient temperature
consistent with these specications is determined by specic operating
conditions in conjunction with board layout, the rated package thermal
resistance and other environmental factors.
Note 3: 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 specied maximum operating junction
temperature may impair device reliability.
Note 4: Voltage transients on the switch pins beyond the DC limit specied
in the Absolute Maximum Ratings, are non disruptive to normal operation
when using good layout practices, as shown on the demo board or
described in the data sheet and application notes.
Note 5: IOUT current is tested in a non-switching DC state. In a switching
environment IOUT accuracy may exhibit variation with factors such as
switching frequency, load current, input/output voltage, and temperature.
See typical performance characteristic curves for predicted variation.
Note 6: The junction temperature (TJ, in °C) is calculated from the ambient
temperature (TA, in °C) and power dissipation (PD, in Watts) according to
the formula:
TJ = TA + (PD θJA), where θJA (in °C/W) is the package thermal
impedance.
Note 7: SYNC frequency range is tested with a square wave. Operation
with 100ns minimum high or low times is assured by design.
