NCP1230集成電路（IC）的ACDC轉換器離線開關規(guī)格書PDF中文資料

NCP1230屬于集成電路（IC）的ACDC轉換器離線開關。由安森美半導體制造生產(chǎn)的NCP1230AC DC 轉換器，離線開關該系列是元器件級控制產(chǎn)品，用于構建將交流市電轉換為直流電（通常電壓大幅降低）的設備。集成和未集成系統(tǒng)主要開關元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來實現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請參見“開關轉換器，SMPS 變壓器”標題。

The NCP1230 represents a major leap towards achieving low standby power in medium-to-high power Switched-Mode Power Supplies such as notebook adapters, off-line battery chargers and consumer electronics equipment. Housed in a compact 8-pin package (SOIC-8, SOIC-7, or PDIP-7), the NCP1230 contains all needed control functionality to build a rugged and efficient power supply.
