electrical characteristics The
l
denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VIN = 15V unless otherwise specified.
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: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formulas:
LTC3823EGN: TJ = TA + (PD 80°C/W)
LTC3823EUh: TJ = TA + (PD 34°C/W)
Note 3: The LTC3823E is tested in a feedback loop that servos VFB to
achieve a specified error amplifier output voltage (ITh).
Note 4: The LTC3823E is guaranteed to meet performance specifications
from 0°C to 85°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
