Dziękuję koledze (diodus) za zainteresowanie się tym tematem i podaniem tutaj ciekawego przykładu zastosowania układu scalonego LM3578 jako przetwornicy napięcia 3,3/5V 600mA co oczywiście można było znależć na pdfie dostępnym na elenocie. Jak widać wszystko ładnie i pięknie ale nie do końca bo jestem ciekaw gdzie teraz dostanę taką kostkę bo u mnie w mieście są 3 dobre sklepy elektroniczne i w ani jednym nie mogę tego dostać :( , również sprowadzanie tego układu scalonego z większych miast na terenie Polski odpada z powodu dodatkowych kosztów więc pozostaje modzić coś na standardowych podzespołach dostępnych w całym kraju lub zbudować przetwornicę na jakimś mosfecie i kawałku drutu nawiniętego na rdzeniu oraz diody prostowniczej na wyjściu ale nie jestem pewien czy to zadziała. Jak narazie jestem w kropce i niewiem zabardzo jakich części użyć do zbudowania przetwornicy DC/DC opisanej w powyższym z moich postów. Doradzcie coś proszę :(

Mozna probowac jeszcze LM2621 (bardzo prosta aplikacja), nie wiem tylko czy nie bedzie jeszcze trudniej dostepny niz LM3578. We Wroclawiu udalo mi sie w National Semiconductors, nie wiem jak w Rzeszowie...
Pozdr.
