The
G
denotes specifications which apply over the specified temperature
range.
Note 1:
T
J
is calculated from the ambient temperature T
A
and power
dissipation P
D
according to the following formula:
LTC1143 series: T
J
= T
A
+ (P

Note 2:
This supply current is for one regulator block. Total supply
current is the sum of Pin 5 and Pin 13 currents. Dynamic supply current
is higher due to the gate charge being delivered at the switching
frequency. See Applications Information.
Note 3:
In applications where R
SENSE
is placed at ground potential, the
off-time increases approximately 40%.
Note 4:
The LTC1143 series is guaranteed to meet specified performance
from 0

C to 70
°
C and is designed, characterized and expected to meet
these extended temperature limits, but is not tested at –40
°
C to 85
