Hi team
Our customer measured the surface temperature using IR thermography in the below condition.
Is it correct the thought to estimate Tj ?
Tj = Tj = Ψjt x Ploss+ Tc
Ψjt:1.0[℃/W]
= 1.0 x 1.62 + 48.8
= 50.42[℃]
Measurement result = 48.8 [℃]
<The conditions>
Input
Vin[Vrms]:23.71
Iin[Arms]:0.346
Pin[W]:8.20
Output
Vout[Vrms]:6.90
Iout[Arms]:0.953
Pout[W]:6.58
Power consumption
Ploss:1.62 (=Pin-Pout)
