主要製品
多くのアプリケーションでは、2次回路のリファレンスが1次回路と同じリファレンス(AC電源)に接続されます。そうしたケースでは、オフライン非絶縁型補助電源を採用し、電源のデューティ·サイクルを変調することにより、インダクタや低コストのトランス(簡易絶縁型)をエネルギー伝達素子として使用して、安定化DC電圧を供給できます。  バック(ステップダウン)トポロジを採用すると、共通端子に対して正の出力電圧を生成できます。負の出力電圧が必要な時は、バックブースト(ステップダウン/ステップアップ)トポロジを採用します。より高い出力電力が必要な時は、代わりに非絶縁型フライバック·コンバータを使用できます。   続きを読む

Our products and solutions

We offer a range of integrated – actually a power MOSFET, PWM controller and protection circuitry in a single package – high-voltage converters providing extremely low stand-by power, high – 800 and 900V – breakdown voltages and a range of protection features to help maximize efficiency and enhance reliability of power supplies. 

In addition, we provide a comprehensive set of hardware and software evaluation and development tools as well as reference designs to enable a fast time to market.
