ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LTC1701E 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:
The LTC1701 is tested in a feedback loop which servos V
FB
to the
midpoint for the error amplifier (V
ITH
= 1.7V unless otherwise specified).
Note 4:
Dynamic supply current is higher due to the internal gate charge
being delivered at the switching frequency.
Note 5:
T
J
is calculated from the ambient T
