STの単一インダクタ同期降圧･昇圧コンバータは、最大3Aの動作電流に対応し、基板面積の削減と電力損失の低減に貢献する4つの低オン抵抗パワーMOSFETを集積しています。リチウムイオン･バッテリで動作するアプリケーションに最適な製品です。
STのバックブースト･レギュレータの主な特徴は以下のとおりです。
- 主要なバッテリ･ソリューションすべてに対応する広い入力電圧範囲（1.8V～5.5V）
- 最大3 MHzの高いスイッチング周波数により設計の小型化に貢献（受動部品のサイズが減少）
- フル･セットのモニタリング機能：同期 / パワーグッド / バッテリ電圧低下検知
- 軽負荷時の節電モードによる効率向上
- 通常の効率：>94%
- 出力電流能力：最大3A
- 1μA未満のシャットダウン電流によりバッテリ寿命の延長に貢献
これらは、主に入力電圧がVIN - VOUT > VINからVIN - VOUT < VINまで変化できる場合に使用されます。
