доброго времени всем… хочу собрать понижающий преобразователь по схеме www.radiokot.ru/circuit/power/converter/11/
но нету указанного силового транзистора - посоветуйте аналоги, желательно например из дохлых БП от компа (если они конечно подойдут). заранее спасибо.
Если уж из компьютерного БП, то думаю любой из тех что часто ставят в дешёвых БП в цепи 3,3 В, например CEP703AL из БП “POWER MASTER” (FA-5-1). Транзисторы в разных БП отличаются по току, так что выбирайте в зависимости от планитуемой нагрузки.
Параметры транзисторов можете найти здесь: www.alldatasheet.com
