input voltage and maximum ambient temperature, verify
that temperature specifications are not exceeded for the
transformer, output diodes, output inductors and output
capacitors. The DPA-Switch is fully protected against
overtemperature conditions by its thermal shutdown
feature. It is recommended that sufficient heat sinking is
provided to keep the tab temperature at or below 115 °C
under worst case continuous load conditions (at low input
voltage, maximum ambient and full load). This provides
adequate margin to minimum thermal shutdown temperature
(130 °C) to account for part-to-part R
monitoring tab temperature, note that the junction-to-case
thermal resistance should be accounted for when estimating
die temperature.
