Guest zg Posted May 30, 2007 Share Posted May 30, 2007 M-ar interesa o schema, sau daca-l pot gasi undeva, ptr un charger la 12V de mobil Siemens (C72). Cel de 220~ are 8,4V in gol, respectiv 5,7 V in sarcina , iar curentul la inceputul incarcarii e undeva in jurul valorii de 600mA. Link to comment
madkat Posted May 31, 2007 Share Posted May 31, 2007 eu as folosi un LM317 pentru treaba asta...incape in carcasa de charger "normala" - doar ca trebuie sa ii pui un mic radiatorcauta datasheetul sa vezi ce piese mai trebuie (vreo 2 rezistente si condensatori)succes Link to comment
MiniTehnicus Posted May 31, 2007 Share Posted May 31, 2007 Am gasit un incarcator de telefon pentru auto care folosea MC34063. http://www.datasheetcatalog.com/datashe ... 4063.shtml Link to comment
madkat Posted May 31, 2007 Share Posted May 31, 2007 eu am recomandat LM-ul din cauza ca nu necesita decat extrem de putine componente externe - in schimb MC-ul nu are nevoie de radiator :yawinkle: Link to comment
