nominal input voltage for airflow rates natural convection
(0.3 m/s (60lfm) to 3.0m/s (600lfm)) with airflow from
Vout(+) pins to Vout(-) pins. Maximum output current vs. ambient temperature at

pins to Vout(+) pins.
Thermal measurement location – top view
The thermal curves provided and the examples 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. The
thermal measurement location (on the IMS board) should be thermal-coupled and monitored, and should not exceed the
temperature limit specified in the de-rating curve above
