Overview

MC34167/MC33167 シリーズは、DC-DC コンバータに最優先で必要な機能を含む高性能固定周波パワー降圧ブースト反転スイッチング・レギュレータです。ステップ・ダウン/電圧反転構成への組み込みに特化して設計されており、外部コンポーネントの数を最小限にします。内部温度補償リファレンス、オンチップ・タイミング・コンポーネントの固定周波数発振器、シングル・パルス・メータリング用ラッチング・パルス幅変調器、高ゲイン・エラー・アンプ、高電流出力スイッチで構成されています。保護機能には、サイクル単位の電流制限、低電圧ロックアウト、サーマル・シャットダウンがあります。低電力スタンバイ・モードもあり、電源電流を 36 µA まで低減します。
