Помогите со схемой Dc-dc конвертер понижающий на 3 В
На плате есть трехштырьковый разъем для выбора выходного напряжения. Между средним выводом разъема и положительным проводам (выход) включите резистор 30 кОм, тогда на выходе регулятора будет 3,1В.
Если с паяльником дружите - посмотрите на микросхемку ST1S10.
Вот простой вариант www.sureelectronics.net/goods.php?id=837
Оптимальнее пункт №3, например от сименса С55 или Нокии 6610. На выходе должно быть напряжение около 5 вольт. Внутри стоит преобразователь на МС 34063. Уменьшаем сопротивление, которое соединяет выход и 5 ногу МС, до значения 1,4 кОм. Получаем на выходе 3 вольта.
