Overview

NCP12510 は高集積 PWM コントローラで、頑丈で高性能のオフライン電源が小型の TSOP-6 パッケージで実現できます。電圧源範囲は最大 35 V、ピーク電流モード制御で動作するジッタード 65 kHz/100 kHz のスイッチング回路をホストします。セカンダリ・サイドの電力が下がり始めると、スイッチング周波数を最低レベルの 26 kHz まで自動的にフォールドバックします。電力がさらに下がると、スキップ・サイクルへ移行してピーク電流を制限します。このコントローラには、過電力保護 (OPP)、過電圧保護 (OVP)、短絡保護などの保護機能が統合されています。NCP12510 は、評判の高いフライバック・コントローラ NCP1250 をベースに改善された、ピン間互換性を持つコントローラです。
