Фирма National Semiconductors выпустила новую линейку микросхем импульсных стабилизаторов LMZxxxxx (SIMPLE SWITCHER) с встроенными индуктивностями и диодами Шоттки. Корпус ТО-TMOD (похож на ТО-220-7). Рабочая частота до 1 МГц, кпд 90-96%. Обвязка, как у обычного линейного ВЕСа. Есть степ-ап варианты до 5 А www.national.com/ds/LM/LMZ10505.pdf и степ-дауны до 3 А www.national.com/ds/LM/LMZ14203.pdf .
По описанию штука прикольная, но цена кусачая. Кто попробует первым, поделитесь впечатлениями, плиз 😃.
Да что то они с ценой намудрили, думаю долго при такой цене, мы не узнаем как оно работает.
