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。 Read more

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.
