Компоненты для зарядки ионисторов
Analog Devices предлагает ассортимент линейных и импульсных преобразователей, а также микросхем на основе переключаемых конденсаторов, которые предназначены для зарядки ионисторов (конденсаторов большой емкости). Эти устройства обеспечивают ограничение входного или выходного тока, автоматическую балансировку заряда ячеек, а также имеют ряд защитных функций, которые делают их уникальными решениями, предназначенными для зарядки ионисторов. Благодаря большому количеству преимуществ, таких как более низкое эффективное последовательное сопротивление и повышенная долговечность при повторных зарядках, ионисторы становятся все более заметной альтернативой аккумуляторам в приложениях, где потребность в подаче энергии превосходит потребность в запасенной энергии.
