In actual systems, the load transient will most likely be of
varying frequency and step size. The power dissipation
of the HIP6200/1 becomes even more difficult to estimate
analytically.
HIP6200 Temperature Rise
The HIP6200/1 junction temperature can be estimated
where:
Θ
JA
is the thermal resistance from junction to ambient.
Example:

In a similar fashion, one could estimate the maximum
allowable power dissipation for given maximum ambient and
transient loading and determine the boundary of maximum
transient frequency.

From Figures 4 and 5, the estimated maximum transient
frequency is obtained for any of the seven cases shown. For
instance, from Figure 4, the maximum transient frequency is
about 4kHz for the 8A transient step and the conditions
stipulated.
