ELECTRICAL CHARACTERISTICS
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:
LTC3717EGN: T
J
= T
A
+ (P
D
130
°
C/W)
Note 3:
The LTC3717 is tested in a feedback loop that adjusts V
FB
to achieve
a specified error amplifier output voltage (I
TH
).
Note 4:
The LTC3717E 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.
