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 LTC3812E-5 is guaranteed to meet performance specications
from 0°C to 85°C. Specications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls. The LTC3812I-5 is guaranteed to meet
performance specications over the full –40°C to 125°C operating
temperature range.
Note 3: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula:
LTC3812-5: TJ = TA + (PD 38°C/W)
Note 4: The LTC3812-5 is tested in a feedback loop that servos VFB to the
reference voltage with the ITH pin forced to a voltage between 1V and 2V.
Note 5: The dynamic input supply current is higher due to the power
MOSFET gate charging being delivered at the switching frequency
(QG fOSC).
Note 6: Guaranteed by design. Not subject to test.
Note 7: 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 8: ICC is the sum of current into NDRV and INTVCC.
The
l denotes specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C, INTVCC = VBOOST = VRNG = VEXTVCC = VNDRV = 5V, VFCB = VSW = 0V,
unless otherwise specied.
