降压转换器拓扑结?深圳晨飞开关电源变压器smps，外部开关与集成开?降压转换器解决方案有许多集成开关和外部开关，后者通常被称为步降或降压控制器。这两种方案具有明显的优缺点，因此在两种方案之间进行选择时必须要考虑到其各自的优缺点?
许多内部开关都具有低组件数量的优势，这一优点使这些开关拥有较小的尺寸，可以用于许多低电流应用中。由于其集成性，在表现出良好 EMI 性能的同时，它们均可以在高温或其他外部可能出现的受影响的条件下得到保护。但是它们也有不足之处，即电流和散热极限问题。而外部开关则提供了更大的灵活性，电流处理能力仅受外部 FET 选择的限制。在负极侧，外部开关具有更多的组件数量且必须得到保护以免受到潜在问题的损坏?
所以我们在使用的时候应该谨慎，以免对器件造成损坏。更多关于开关电源变压器的资料请登录晨飞官网http://www.chenfeipower.com进行在线咨询 ，我们会为您提供最好的服务
