Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC1876E is guaranteed to meet performance specifications
from 0
°C to 70°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 3: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formulas:
LTC1876EG: TJ = TA + (PD • 95°C/W)
Note 4: The LTC1876 is tested in a feedback loop that servos VITH1, 2 to a
specified voltage and measures the resultant VOSENSE1, 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 specified for an inductor peak-
to-peak ripple current
≥40% of IMAX (see Minimum On-Time
Considerations in the Applications Information section).
Note 8: VFREQSET pin internally tied to 1.19V reference through a large
resistance.
Note 9: Current limit guaranteed by design and/or correlation to static test.
Note 10: 100% tested at wafer level.
ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VIN = 15V, VRUN/SS1, 2 = 5V, AUXVIN = 3V unless otherwise noted.
