　　使用集成隔离反激式转换器降低设计复杂度

　　电流隔离是一个关键要求的电源设计的应用程序工作电压高或接近人类。反激转换器提供了一个有效的隔离电源解决方案，但可以提出显着的设计挑战，以确保在宽负载范围内的稳定输出

　　为了帮助克服这些挑战，我们将描述的问题，然后使用一个特定的模型转换器作为一个例子来指定一些考虑的因素，以实现一个成功的设计。

　　The challenges associated with producing an efficient power supply based on flyback topology require the knowledge of experts in power design. Today‘s demand for faster delivery of smaller， simpler designs exacerbates the difficulty of working with traditional approaches. For designers， newer integrated devices such as the ROHM BD7F series offer an effective solution for less complex designs with a faster time to market.

　　Among converter topologies， the flyback converter offers isolation， and requires relatively few parts even in discrete designs. Fundamentally， a flyback converter is a buck-boost converter utilizing a transformer. While the flyback converter’s switching topology enables output regulation， its transformer provides galvanic isolation and enables you to select the input/output voltage ratio by selecting an appropriate winding ratio.
