PWMコントローラ

STのパルス幅変調(PWM)コントローラのポートフォリオは、絶縁型と非絶縁型のAC-DCおよびDC-DCスイッチング電源に対応しています。これらの電源は、中電力から高電力のスイッチング電源(SMPS)向けのシングルエンド(フライバック、フォワードまたは擬似共振など)とダブルエンド(非対称ハーフブリッジなど)の双方で最も一般的なトポロジをベースにしています。

革新的なPWMコントローラにより、コンバータの効率を向上し、設計コストを低減

STのPWMコントローラの製品ラインアップには、多数の先進的デジタル・コントローラが含まれています。その革新的なソリューションにより、幅広い負荷条件、特に高電圧起動などの軽負荷時にコンバータの効率を最適化します。

これらのPWMコントローラICは、屋外向けアプリケーション用に拡張された動作温度範囲でも、包括的な保護機能を提供することで、高い堅牢性と信頼性を実現します。その結果、外付け部品点数を削減に貢献し、コンバータのサイズとコストを最小限に抑えることができます。

UC(電圧モード)とSG(電流モード)シリーズの業界標準コントローラも、よりメインストリームのSMPS設計に利用できます。

Compact quasi-resonant PWM controller for ultra-low standby power supplies

The STCH03 features a built-in high-voltage start-up circuit with zero power consumption, fully integrated blocks for primary-side constant-current output regulation and advanced power management, making it the best choice for high efficiency and ultra-low standby consumption power supplies with excellent dynamic performance.

Designed to provide a constant output current (CC) regulation using primary-sensing feedback, the STCH03 reduces BOM costs and simplifies your design as a dedicated current reference IC and current sensor are no longer required.

Moreover, an embedded frequency jitter technique helps reduce EMI noise.
