説明

RRW43110は、高度な同期整流（SR）コントローラで、MOSFETおよびGaNデバイスの両方に対応します。 ルネサス独自のロスレスVDSセンシング技術を採用し、半波LLC（HWLLC）やその他のハーフブリッジ共振コンバータなど、複数のトポロジにおいて最大300 kHzのスイッチング周波数で動作します。

外付けパワースイッチを駆動して二次側整流ダイオードを置き換えることで、広範な動作条件下でも高効率を実現します。 その汎用性により、RRW43110は次世代の高電力密度電源に最適で、最大3W/cm³の高密度設計および最大500Wの出力に対応します。

また、RRW43110は最大48V以上の広い出力電圧に対応し、柔軟な二次側整流を必要とするさまざまな電源アプリケーションに対応します。

さらに、低負荷および無負荷時の効率を最適化するため、低消費電力モードおよびスリープモードもサポートしています。
