使用集成隔離反激式轉換器降低設計復雜度

　　電流隔離是一個關鍵要求的電源設計的應用程序工作電壓高或接近人類。反激轉換器提供了一個有效的隔離電源解決方案，但可以提出顯著的設計挑戰，以確保在寬負載范圍內的穩定輸出

　　為了幫助克服這些挑戰，我們將描述的問題，然后使用一個特定的模型轉換器作為一個例子來指定一些考慮的因素，以實現一個成功的設計。

　　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.
