Overview

NCP1653は、連続伝導モード（CCM）力率補正（PFC）ブースト回路向けに設計されたコントローラです。固定スイッチング周波数67 kHz（NCP1653A）/100 kHz（NCP1653）のフォロワー・ブーストか低電圧で動作します。フォロワー・ブーストには、出力電圧を低減、ひいてはインダクタと電源スイッチのサイズを縮小しコストを低減するというメリットがあります。DIP-8またはSO-8パッケージで、外部コンポーネントの数を最小限にし、CCM PFCの実装を大幅にシンプル化します。高度な安全保護機能も内蔵しています。NCP1653は堅牢でコンパクトなPFC段向けのドライバです。
