Description
В проекте представлена простая конструкция ШИМ-регулятора, с помощью которой можно легко переделать компьютерный блок питания, собранный на контроллере, отличном от популярного **TL494**, в частности, DR-B2002, DR-B2003, SG6105 и прочих, в блок питания с регулируемым выходным напряжением и ограничением тока в нагрузке.
