LTC3709
ELECTRICAL CHARACTERISTICS The ● denotes specifications which apply over the full operating
temperature range, otherwise specifications are at T_A = 25°C. V_CC = DRV_CC = 5V, unless otherwise noted.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: T_J is calculated from the ambient temperature T_A and power
dissipation P_D as follows:
LTC3709EUH: T_J = T_A + (P_D • 34°C/W)
Note 3: The LTC3709 is tested in a feedback loop that adjusts V_FB to
achieve a specified error amplifier output voltage (I_TH).
Note 4: The LTC3709E 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 5: R_DS(ON) limit is guaranteed by design and/or correlation to static
test.
