PI Expert Online

PI Expert Online允许电源设计师输入规格参数，然后可自动生成围绕Power Integrations某一IC产品系列的电源转换方案。PI Expert Online可提供构建和测试工作原型所需的所有必要信息，包括完整电路原理图、物料清单(BOM)、电路板布局建议以及详细的电气参数表。

PI Expert Online还可提供完整的变压器设计，包括磁芯尺寸、线圈圈数、适当的线材规格以及每个绕组所用的并绕线数。此外，还可生成详细的绕组机械装配说明。

PI Xls Designer已集成到PI Expert Online中，PI Xls Designer是基于设计表格的应用程序，能让电源设计师在设计过程中获得更多的控制。同时，也提供包括详细的绕组机械装配说明在内的变压器构建支持。PI Xls Designer根据您提供的有关输入、输出以及其他所有必需的规格参数来执行必要的计算，以设计和评估电源转换方案。
