Maximum balanced load (Io1=Io2) output current vs.
ambient temperature at nominal input voltage for airflow
rates natural convection (60lfm) to 600lfm with airflow from
pin 3 to pin 1.
Maximum Io1 output current (Io2=0) vs. ambient
temperature at nominal input voltage for airflow rates
natural convection (60lfm) to 400lfm with air flow from pin 3

The thermal curves provided and the example given above are based upon measurements made in Innoveta’s
experimental test setup that is described in the Thermal Management section. Due to the large number of variables in
system design, Innoveta recommends that the user verify the module’s thermal performance in the end application.
