在开关面板的电源设计中，AC220用开关电源转为5V，输出端通过识别芯片转为出A口和C口，一些厂家会用ACDC电源模块做这部分，为了进一步降低物料成本，本文推荐用必易微的KP23132MSGA+ KP41140SGA提供高效率5V/2A电源方案。

图1：开关面板电源设计框图

必易微的KP23132MSGA+ KP41140SGA有如下优势特点：

1、ACDC芯片KP23132MSGA内置800V高压功率三极管，最大功率达到12W。芯片采用多模式原边控制方式，并且谷底开通，实现系统高效率。输出恒流、恒压调整率小于±5%，利用集成的线损补偿功能，可获得高性能的恒压输出表现。另外采用KP23132MSGA可以工作无异音，同时可保证优异的动态性能；

2、同步整流功率开关KP41140SGA是可替代反激电源中副边的肖特基二极管，利用内置MOSFET超低导通阻抗提升系统效率。芯片支持DCM模式和QR模式，并适用于High Side 和 Low Side 配置，控制V_DD无需V_DD辅助绕组供电，内置高压供电模块，节约成本；

3、在保护功能方面，KP23132MSGA集成多种保护功能：输出短路保护、输出过压保护功能、逐周期限流保护、过热保护、V_DD过压、欠压和箝位保护等。KP41140SGA同样拥有V_DD欠压保护、钳位保护等；

4、KP23132MSGA和KP41140SGA均采用通用封装SOP8，工作温度达到-40~85℃。
