ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LTC3406BE 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:
T
J
is calculated from the ambient temperature T
A
and power
dissipation P
D
according to the following formula:
LTC3406B: T
J
= T
A
+ (P
D
)(250
°
C/W)
Note 4:
The LTC3406B is tested in a proprietary test mode that connects
V
FB
to the output of the error amplifier.
Note 5:
Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
Note 6:
This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125
°
C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
