Импульсные стабилизаторы
Компания Analog Devices предлагает широкий спектр импульсных стабилизаторов, которые работают в повышающем, понижающем и инвертирующем режимах. Эти компоненты способны формировать фиксированное или регулируемое выходное напряжение и обеспечивают выходной ток до 2 А. Компоненты линейки импульсных стабилизаторов ADI обладают такими особенностями, например, как детектирование пониженного напряжения батареи, регулируемый пользователем предельный ток, несколько вариантов частоты коммутации, и уменьшенное количество необходимых внешних компонентов. Это семейство универсальных продуктов с высокой степенью интеграции предназначено для минимизации числа внешних компонентах в системах, где предъявляются жесткие требования к габаритам.
