Stresses above those listed under absolute maximum ratings
may cause permanent damage to the device. This is a stress
rating only and 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
Absolute maximum ratings apply individually only, not in
combination.
The ADP5043 can be damaged when the junction temperature
limits are exceeded. Monitoring ambient temperature does not
guarantee that the junction temperature is within the specified
temperature limits. In applications with high power dissipation
and poor thermal resistance, the maximum ambient temper-
ature may have to be derated. In applications with moderate
power dissipation and low PCB thermal resistance, the maximum
ambient temperature can exceed the maximum limit as long
as the junction temperature is within specification limits. The
junction temperature of the device is dependent on the ambient
temperature, the power dissipation of the device (P

mum junction temperature is calculated from the ambient
temperature and power dissipation using the formula
