Цифровое управление питанием

Цифровые контроллеры преобразователей постонного напряжения работают в режиме управления напряжением и имеют выделенные блоки для измерения входного напряжения, входного тока, выходного напряжения, выходного тока и температуры. Они также содержат интегрированную электрически стираемую/программируемую память (EEPROM) для сохранения настроек, используемых при работе в автономном режиме.
