ADP1710/ADP1711
Current and thermal limit protections are intended to protect
the device against accidental overload conditions. For reliable
operation, device power dissipation must be externally limited
so junction temperatures do not exceed 125°C.

THERMAL CONSIDERATIONS

To guarantee reliable operation, the junction temperature of the
ADP1710/ADP1711 must not exceed 125°C. To ensure the
junction temperature stays below this maximum value, the user
needs to be aware of the parameters that contribute to junction

temperature changes. These parameters include ambient
temperature, power dissipation in the power device, and thermal
resistances between the junction and ambient air (θ JA ). The θ JA

number is dependent on the package assembly compounds used
and the amount of copper to which the GND pins of the package
are soldered on the PCB. Table 5 shows typical θ JA values of the

P D = [( V IN – V OUT ) × I LOAD ] + ( V IN × I GND )
where:
I LOAD is the load current.
I GND is the ground current.
V IN and V OUT are the input voltage and output voltage,
respectively.

Power dissipation due to ground current is quite small and can
be ignored. Therefore, the junction temperature equation

As shown in Equation 4, for a given ambient temperature, input
to output voltage differential, and continuous load current,
there exists a minimum copper size requirement for the PCB to
ensure the junction temperature does not rise above 125°C. The
following figures show junction temperature calculations for
different ambient temperatures, load currents, V IN to V OUT
differentials, and areas of PCB copper.
