    Calculate thermal resistance of heatsink required

    So if i use a Vin as 18v use the adjustable resistor and set an output of 12v and am drawing 5amps load on a device that is connected on the output. Using the formula Pd=Vin-Vout*Iout Pd = 18v-12v*5=30W For the control calculation: JuncT = T(amb)+Pd(θHsink+θJct-cas+θcas-Hsink) I would...

    Calculate thermal resistance of heatsink required

    Just noticed the max 'Iout' is actually 7.5A not 1A
