基于DPA-Switch的反激式开关电源设计

Design of the Flyback Switching Mode Power Supply Based on DPA-Switch

DPA-Switch是高集成度DC/DC转换芯片,集PWM控制器和MOSFET于一体,其电路简单,性能优异。文中利用DPA-Switch设计了一个单端反激式多路输出开关电源,简要介绍了变压器的绕制。实验结果表明该电源运行可靠,输出稳定。

DPA-Switch is highly integrated DC/DC converter ICs with simple circuit and high performance, which integrated with PWM controller and MOSFET. A one-port flyback multiple output switching mode power supply circuit is designed based on DPA Switch and the winding of transformer is briefly introduced. The experiment results show that the power supply has reliable working performance and stable output.
