VIPer®高压转换器系列产品由集成了PWM控制器和700 V HV垂直功率MOSFET的单片集成电路IC组成。

VIPerPlus具有800 V耐雪崩功率MOSFET和顶级PWM控制器,静态功耗低于30 mW(@265 VAC)。该产品同样配有全面保护特性,并支持不同的拓扑结构。

Altair系列产品具有内置900 V耐雪崩功率MOSFET和PWM控制器,专为无光耦应用而设计,从而可显著减少元件数量。

高电子迁移率晶体管(GaN HEMT)技术的引入丰富了VIPerGaN系列高压功率转换器。GaN晶体管的使用带来了更高的功率密度、效率,以及开关频率,帮助人们研发出体积更小且重量更轻的PCB,简化了SMPS的设计,提高了整体性能。

High voltage converters


新推出的这款 VIPer0P 高压转换器,带有简化的电磁兼容抖动固定频率电流模式PWM控制,采用零功率模式(ZPM),可实现低于4 mW(在230 VAC条件下)的极低功耗。 当低电压输入/输出引脚(OFF或ON)被下拉至地时,VIPer0P能够进入和退出ZPM,因此,可使用体积小、成本低的安全极低电压(SELV)开关来替代笨重的主开关。 VIPer0P内置了一系列保护措施,包括过流保护(OCP)、VCC箝制、最大占空比和通量失控,使得设计的SMPS更加稳定安全。

VIPer0p是所有7 W以下、拥有宽广输入电压范围的SMPS器件的理想选择,包括:

  • 符合EuP Lot6能源标准的家用电器
  • 工业设备或消费类数码产品

使用 STEVAL-ISA174V1 非隔离反激式6W SMPS评估板来全面考察零功率模式VIPer0P高压转换器的主要优势。
