DIP-8封裝單片高壓功率型開(kāi)關(guān)電源模塊

摘要：普通DIP-8封裝的集成電路，內(nèi)設(shè)電流控制PWM，有自給電源，開(kāi)啟后，又自動(dòng)加入自激電源；同時(shí)，還內(nèi)置了730V／0.7A的功率MOSFET。電路結(jié)構(gòu)精練，過(guò)熱﹑過(guò)流和過(guò)壓等保護(hù)功能齊全，穩(wěn)定可靠程度高，響應(yīng)速度快，穩(wěn)壓精度高，適用于電網(wǎng)波動(dòng)大的場(chǎng)合，也適用于負(fù)載有波動(dòng)的場(chǎng)合，并適宜于兩臺(tái)及以上電源并聯(lián)運(yùn)行。 敘詞：DIP-8封裝 VIPer22A 單片開(kāi)關(guān)電源功率變換器 電流控制PWM 自給電源 自激電源 Abstract：The DIP-8 packaging IC consists of current-controlled PWM, self-sufficient power and build-in 730V/0.7A MOSFET. When the self-sufficient power is started, a self-energizing power will be switched on. It is desirable for the applications which have horrid grid voltage fluctuations and little load changes with its features of compact structure, high reliability, fast response, constant voltage of high accuracy, powerful overheat, overcurrent and overvoltage protection functions.
