車載向けにAEC-Q100準拠のデュアル同期型DC/DCレギュレータ「ISL78228」を発売【インターシル】

ISL78228はデュアル出力のステップダウンDC/DCレギュレータで、独立した800mA出力を2系統備えています。パッケージサイズは3mm×3mmと小型で、スイッチング周波数は2.25MHzと高いため、実装面積が限られる車載アプリケーションあるいは産業用アプリケーションに最適な製品です。入力電圧範囲は2.75Vから5.5Vと広いため、車載システム内の電源が出力する一般的な3.3Vレールまたは5Vレールで動作が可能です。また過渡応答を高速化する電流モード補償回路を内蔵し、さらにドロップアウトの小さい100%デューティサイクル動作が可能で、外付け補償回路が必要ありません。
