DIP-8封裝單片高壓功率型開關電源模塊

摘要：普通DIP-8封裝的集成電路，內設電流控制PWM，有自給電源，開啟后，又自動加入自激電源；同時，還內置了730V／0.7A的功率MOSFET。電路結構精練，過熱﹑過流和過壓等保護功能齊全，穩定可靠程度高，響應速度快，穩壓精度高，適用于電網波動大的場合，也適用于負載有波動的場合，并適宜于兩臺及以上電源并聯運行。 敘詞：DIP-8封裝 VIPer22A 單片開關電源功率變換器 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.
