摘　　要：TOPSwitch- 器件为三端单片开关电源,是一种将PWM和MOSF ET合二为一的新型集成芯片。与普通线性稳压电源相比其优点为体积小、重量轻,并且密度高、价格低;采用它制作高频开关电源,不仅简化了电路,同时可以改善电源的电磁兼容性能,且降低了制作成本。介绍了一个多路输出开关电源的设计。TOPSwitch-Ⅱ device belongs to three-terminal off-line PWM switch. It is a new type of IC which merges PWM and MOSFET. It has many advantages: small volume, light weight, high density and low cost.High frequency switching power supply made from it can not only simplify the circuit, but also can improve the EMC characteristics and reduce the cost. This paper mainly discusses how to design a TOPSwitch Ⅱ power supply with several output.
