KA5L0265RYDTU集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)規(guī)格書PDF中文資料

KA5L0265RYDTU屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由安森美半導體公司制造生產(chǎn)的KA5L0265RYDTUAC DC 轉(zhuǎn)換器，離線開關(guān)該系列是元器件級控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)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(guān)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(guān)轉(zhuǎn)換器，SMPS 變壓器”標題。

Description

The Power Switch product family is specially designed for

an off-line SMPS with minimal external components. The

Power Switchconsist of highvoltage power SenseFET and

current mode PWM IC. IncludedPWM controller features

integrated fixed oscillator, under voltage lock out, leading edge

blanking, optimized gate turn-on/turn-off driver, thermal shut

down protection, over voltage protection, and temperature

compensated precision current sources for loop

compensation and fault protection circuitry-compared to

discrete MOSFET and controller or RCC switching converter

solution. The Power Switchcan reduce total component count,

design size, weight and at thesame time increase efficiency,

productivity, and system reliability. It has a basic platform

well suited for cost-effectivedesign in either a flyback

converter or a forward converter.
