概要

概要

VIPERGAN65は、中出力の擬似共振ZVS（スイッチのターンオン時にゼロ電圧スイッチング）フライバック･コンバータ用に設計された高電圧AC-DCコンバータです。ワールドワイド電源電圧範囲で最大65Wを出力することができます。

VIPERGAN50は、きわめて柔軟で使いやすいチップを実現する機能を統合し、高効率オフラインAC-DC電源の設計をサポートします。ダイナミック･ブランキング･タイム機能と、常にドレイン共振の谷で電源スイッチをオンにするバレー同期機能によるZVS擬似共振動作が、スイッチング損失を抑え、入力ラインおよび負荷条件にかかわらず全体の効率を最大化します。高機能なパワー･マネージメントは静止電流が少なく、スタンバイ状態での消費電力を抑制します。フィード･フォワード補正で、入力電圧範囲全体で最大出力のピーク電力の変動を最小限に抑えます。

また、上記の機能に加え、出力の過電圧保護、過熱保護（OTP）、過負荷保護（OLP）、コンバータの電源をオンおよびオフにする入力電圧レベルを設定するブラウンイン/アウト保護、入力ラインの電圧が異常に上昇した場合にシステムを保護する入力過電圧保護（iOVP）といった最終製品の安全性と信頼性を大幅に強化する保護機能を提供しています。すべての保護は自動再復帰モードです。
