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 LTC3827E-1 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 LTC3827I-1 is guaranteed to meet
performance specications over the –40°C to 85°C operating temperature
range.
Note 3: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula:
TJ = TA + (PD 95 °C/W)
Note 4: The LTC3827-1 is tested in a feedback loop that servos VITH1, 2 to
a specied voltage and measures the resultant VFB1, 2.
Note 5: Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency. See Applications Information.
Note 6: Rise and fall times are measured using 10% and 90% levels. Delay
times are measured using 50% levels.
Note 7: The minimum on-time condition is specied for an inductor
peak-to-peak ripple current ≥ 40% of IMAX (see minimum on-time
considerations in the Applications Information section).
