2.3 Thermal Images

The following thermal images show a top and bottom view of the board. The ambient temperature was 20°C with no forced air flow.

The following conditions apply to these thermal images.

  • 400VDC: PIN = 8.1W, VOUT1 = 12.01V, 0.25A; VOUT2 = 12.45V, 0.0094A;
    VOUT3 = 11.99V, 0.25A; Efficiency = 76%
