Nesto oko hladjenja...
#13
Bas ovi MOSFET-ovi od IR-a su u pitanju:

http://www.irf.com/product-info/datashee...rfp240.pdf

Pogledaj u odeljku Thermal resistance, navode 0.24c/w za namazan tranzistor bez liskuna. S tim da je to tipicna vrednost , min i max nisu naveli.

Onaj najbolji primerak iz prethodnog posta ispada da mu liskun unosi oko 0.1 C/W, a onom najgorem od 0.708c/w liskun unosi oko 0.46C/W.

Usput ako je niski napon u pitanju, a volis avanture, dobra eloksaza hladnjaka je vrlo pristojan izolator - oksid aluminijuma.
Elektrolitski kondenzatori rade tako nekako Smile
Citao sam negde koliko volti je probojni napon po mikrometru Al oksida, al da me ubijes ne secam se gde, mislim da je neki Ap note od Nichicon-a ili PAnasonic-a.....
