Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL DATA
The ADP1655 may be damaged if the junction temperature
limits are exceeded. Monitoring T
is within the specified temperature limits. In applications with
high power dissipation and poor thermal resistance, the maximum
T
dissipation and low PCB thermal resistance, the maximum T
can exceed the maximum limit as long as the T
