高電圧コンバータ

STの高電圧AC-DCコンバータは、高度なパルス幅変調(PWM)コントローラと高電圧パワーMOSFETをワンパッケージに集積しているため、

数ワットから数十ワットまでの出力範囲のオフライン・スイッチング電源(SMPS)に適しています。幅広い製品ポートフォリオにより、擬似共振、フライバック、バック、絶縁、非絶縁等の主要トポロジに最適な製品を選択できます。また、非常に厳しい信頼性目標を満たすためにきわめて多くの保護機能を搭載し、コスト最適化のために外部部品数は最小限に抑えられています。

VIPer®高電圧コンバータ・シリーズは、PWMコントローラと700V高電圧バーティカル・パワーMOSFETを集積したモノリシックICで構成されています。

VIPerPlusシリーズは、800Vのアバランシェ耐性を持つパワーMOSFETと最先端のPWMコントローラを特徴とし、スタンバイ時の消費電力はわずか30mW(265VAC時)未満です。また、豊富な保護機能を搭載しており、さまざまなトポロジをサポートします。

Altairシリーズは、900Vのアバランシェ耐性を持つパワーMOSFETおよびフォトカプラレス用に設計されたPWMコントローラを内蔵しているため、部品数が大幅に削減されます。

高電圧電源コンバータのVIPerGaNシリーズは、GaN HEMTテクノロジーの導入により拡充されています。GaNトランジスタを使用すると、結果としてPCBの小型化、軽量につながるため、高電力密度、高効率、高スイッチング周波数が実現され、スイッチング電源の設計が簡素化されて、全体的な性能が向上します。

High voltage converters

New VIPer0P with unique zero-power mode

Introducing the VIPer0P high-voltage converter with jittered fixed-frequency current-mode PWM control for simplified EMI compliance and zero-power mode (ZPM) with an astounding < 4 mW (at 230 VAC) consumption. VIPer0P can enter and exit ZPM when the low voltage input/output pins (OFF or ON) are pulled to ground so a small and inexpensive safety extreme low voltage (SELV) switch can replace the bulky mains switch. The VIPer0P embeds a set of protections – including over-current protection (OCP), VCC clamp, maximum duty cycle and flux runaway – to enable a more robust and safer SMPS design.

The VIPer0p is ideal for all SMPS up to 7 W having a wide input voltage range including:

  • Home appliances compliant with EuP Lot6 energy regulation
  • Industrial equipment or digital consumer goods

Explore all the key benefits of the VIPer0P high-voltage converter with unique zero-power mode with the STEVAL-ISA174V1 non-isolated, flyback 6 W SMPS evaluation board.
