Flow Prolonged operation without airflow at low input voltage and at at full power will cause the MOSFET’s and Diodes to over- heat. A fan with a minimum of 200 LFM should always be provided. Figure 2 illustrates the temperature rise of various components with no airflow. The ambient was 25°C, and VIN
