Overview

NCP1075A/NCP1075B 製品は、固定周波数電流モード・コントローラと 700 V MOSFET を統合したものです。非常に一般的な PDIP 7 パッケージを 2 つの異なったピンアウトで提供します。ソフトスタート、周波数ジッタリング、ショート保護、スキップ・サイクル、最大ピーク電流セットポイント、ランプ補償、ダイナミック自己給電 (DSS、補助巻線不要) などが高レベルで統合されています。他のモノリシック・ソリューションと異なり、NCP1075A/NCP1075B は本来的に静かです。公称負荷運転時、利用可能な周波数のいずれか (65 /100 kHz) にスイッチします。出力電力需要が減少すると、周波数フォールドバック・モードへ自動で移行し、低負荷で優れた効率を発揮します。電力需要がさらに減少すると、スキップ・モードへ移行して、スタンバイ消費を無負荷状態まで低減します。保護機能には、過負荷やショートのイベントを検出するタイマ、自動リカバリによる過電圧保護などがあります。AC 入力ライン電圧検出により、低入力電圧状態 (電圧低下) や入力ラインの電圧が高すぎる場合の致命的な暴走を防止します (AC ライン過電圧保護)。これにより、過電圧保護では、高入力電圧状態でのすべての内部遅延の補償や、最大出力電流機能の最適化もできます。スタンバイ性能向上のため、補助巻線を接続して DSS 動作を停止し、高圧線での入力電力消費を 50 mW より下に低減します。
