VIPerPlus系列高压转换器配置领先市场的PWM(脉宽调制)控制器的800 V耐雪崩(avalanche-rugged)MOSFET(场效应管),待机功耗极低(230 VAC输入电压下,待机功耗仅为4mW),在宽的负载范围内效率很高。VIPerPlus器件使SMPS(开关电源)的设计达到严格的节能标准,提高了可靠性和可扩展性,并将系统组件数量减少一半。

高压转换器

  • VIPer0P具有独特的零功率模式和宽的输入电压范围(功率可高达7W),是所有开关电源的理想选择。该器件还集成了一个误差放大器和一个逻辑电平MOSFET(场效应管),简化了采用5V输出的超低功耗SMPS(开关电源)(降压或反激)的设计。
  • VIPerPlus系列1系列集成了一个误差放大器和一个逻辑电平MOSFET(场效应管),据此能够建立一个采用5V输出的简单超低功耗SMPS(开关电源)(降压,降压-升压转换器和反激式)。独特的过压保护和18 VDC漏极电压启动功能使它更加稳健可靠。
  • VIPerPlus series 5系列采用准谐振拓扑以提供高效率。
  • VIPerPlus series 6系列集成了一个误差放大器,以满足先进的SMPS(开关电源)要求,从而减少系统元件数量。
  • VIPerPlus series 7系列采用了输入欠压和过压保护,提高了可靠性。
  • VIPerPlus series 8系列具备维持1至2秒过载的峰值功率能力,系统稳定性高。

高压转换器

VIPer11 enables ultra-low consumption SMPS for 5-30 V output and ultra-wide range input voltage

Integrating an 800 V avalanche-rugged logic-level MOSFET with PWM current-mode control and multiple protection circuits, the  VIPer11 high-voltage converter enables designers to create a simple and ultra-low consumption SMPS in flyback, buck, or buck-boost configuration with a 5 V output. It is ideal for low-power applications in home appliances, building, lighting, motion control as well as small industrial and consumer applications. Its integrated high-voltage start-up and sense-FET, error amplifier, and oscillator with jitter minimizes the number of external components required to design a complete application.
