降圧レギュレータ(DC-DC降圧スイッチング・レギュレータ)は、入力電圧を降圧し、安定した出力電圧を提供するDC-DCコンバータです。
STのモノリシック降圧レギュレータICは、最大61Vの入力電圧および最大4Aの出力電流を高いスイッチング周波数で供給します。
STの降圧レギュレータは、過電流、過電圧、過熱保護などの包括的な保護機能を搭載しているため、平均故障間隔(MTBF)の延長、必要な外付け部品数の削減、その結果としての部品(BOM)コストの低減に貢献します。

さまざまなアプリケーション要件に対応するモノリシック降圧レギュレータIC
製品タイプ:適切な降圧レギュレータを選択する方法
幅広い要件に対応可能なSTの降圧レギュレータのラインアップをご紹介します。



低消費電力降圧コンバータは、低負荷時の超低静止電流と高い効率を特徴としているため、これらのアプリケーション要件を満たします。

ただし、EMI規格への適合を難しくするだけでなく、ノイズの影響を受けやすいアプリケーションに干渉する可能性もあるスイッチング・ノイズがもたらされます。
低ノイズ降圧コンバータは、設計者がこれらの課題に対処するために役立ちます。


短いオン時間により、入力から出力への大きな変換率を確保しながらも、高いスイッチング周波数が維持されます。

About buck converters
How does a buck converter work?
A buck converter usually uses two switches and an inductor to make a voltage controlled current source that interacts with the parallel combination of output capacitor and load, to generate the desired output voltage (VOUT < VIN).
Where and why is a buck converter used?
A buck converter is used to step down the voltage of a given input to achieve the required output voltage. Buck converters can be used in many applications, including smartphones, tablets, battery-powered equipment, industrial power systems and point-of-load supplies.
What are the advantages of a buck converter?
Buck converters offer a more efficient solution with fewer, smaller external components. They can step-down voltages using a minimal number of components. In the same time, they offer a lower operating duty cycle and higher efficiency across a wide range of input and output voltages.
