スイッチングレギュレータ

RECOMの 3 ピンスイッチングレギュレータは効率の悪いリニアレギュレータとそのまま置き換えられる高効率製品です。最大 97% の高効率により大型ヒートシンクが不要となるほか、3 端子レギュレータとピン互換性があるため既存設計への後付け改良が簡単です。スルーホールタイプ、リード線付きタイプ、SMD 実装タイプの各パッケージを用意しています。

標準的な SIP3 パッケージに加え、RECOMは 3D パワーパッケージ技術を活用しインダクタ内蔵の先進的な SMD 非絶縁型スイッチングレギュレータを開発しました。

設計導入プロセスを短縮するため、RECOMはこれらの降圧コンバータモジュール用評価ボードを提供しており、実際の使用環境下での性能検証を迅速に実施できます。

    よくあるご質問

    スイッチングレギュレータは高効率な直流電圧変換が必要な組み込みシステム、産業電子機器、IoT デバイス、負荷点（PoL）用途で使用されます。またエネルギー効率が重要な通信システムや電池駆動機器にも広く採用されています。小型サイズのため実装スペースに制限がある設計に適しています。
    はい。RECOM R-78 シリーズをはじめ多くのスイッチングレギュレータがリニアレギュレータとそのまま置き換え可能に設計されており、高効率かつ発熱を低減します。大幅な再設計を行わず既存システムをアップグレードでき、多くの場合システム全体の性能と放熱特性も改善します。
    高効率スイッチングレギュレータは電力損失と発熱を抑え、多くの場合ヒートシンクが不要になるとともにシステム全体の信頼性を向上させます。消費電力の低減と優れた放熱性能につながり、放熱対策に制限のある小型・密閉型システムに特に有効です。
    負荷点コンバータは負荷の近傍に実装する DC/DC レギュレータのことで、局所的に電圧安定化を行うことで小型システムの効率と電力供給を改善します。電力ラインの電圧降下とノイズを低減するほか、負荷変動時の過渡応答性を高めます。
    選定には入力電圧範囲、出力電流、効率、パッケージ種類、絶縁の要否が影響します。RECOMは多様なラインナップで各種設計ニーズに対応可能です。最終製品の放熱環境や実装スペースの制約も考慮することが重要です。
