Note 1: Stresses beyond those listed under Absolute Maximum Ratings 
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC3104 is tested under pulsed load conditions such that

. The LTC3104E is guaranteed to meet specifications from
0癈 to 85癈 junction temperature. Specifications over the 40癈 to
125癈 operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3104I is guaranteed over the full 40癈 to 125癈 operating junction
temperature range. The junction temperature (T
J
) is calculated from the
ambient temperature (T

) and power dissipation (P

) according to the
formula:

is the package thermal impedance. Note the maximum ambient
temperature consistent with these specifications is determined by specific
operating conditions in conjunction with board layout, the rated package
thermal resistance and other environmental factors.

Note 3: This IC includes overtemperature protection that is intended to 
protect the device during momentary overload conditions. The maximum
rated junction temperature will be exceeded when this protection is active.
Continuous operation above the specified absolute maximum operating
junction temperature may impair device reliability or permanently damage
the device.
Note 4: Specification is guaranteed by design.
Note 5: The LTC3104 has a proprietary test mode that allows testing in a 
feedback loop which servos V
FB
 to the balance point for the error amplifier.
