在工业产品中，系统硬件工程师经常会使用到DC-DC隔离电源，例如：CAN通信、RS485通信等都需要进行隔离传输，系统隔离是增强工业产品可靠性的重要保证。如图1所示，为RS485通信示意图：

图1：RS485通信示意图

如果系统硬件工程师不具备专业的电源设计经验，通常会购买隔离电源模块，其优势在于体积小、使用方便，缺点是价格昂贵且灵活性较差。针对此类应用，其输入输出电压通常都低于24VDC，功率一般在5W以内，ROHM推出了一款无需光耦反馈的隔离型FLYBACK转换器（型号为BD7F100），配合反激变压器可实现稳定的输出电压。如图2所示：

图2：无需光耦反馈的隔离型FLYBACK电源

由图2可以看到，采用ROHM的BD7F100隔离型FLYBACK转换器设计反激电源，无需常规反激电源反馈回路中的隔离光耦，大幅度减少了外围器件的个数，同时采用独创的适应型导通时间控制技术，无需外接相位补偿元件，可实现简单、高性能的隔离型电源应用。

BD7F100隔离型FLYBACK转换器内部集成了60V耐压MOS管、反激控制器以及原边电压反馈电路，其输入电压支持3V~40V，典型开关频率为400kHz，过流点为1.25A。通过简单的外围电路设计，可以实现5W以内的功率输出，图3给出了一款24V转5V的典型应用电路：

图3：24V转5V典型应用电路

在图3电路中，给出了BD7F100反激转换器的外围电路，包括元件和隔离变压器的具体型号和参数，可以帮助系统硬件工程师快速、高效的设计出小体积、高可靠性的DC-DC隔离电源，缩短研发周期，提高性价比。
