ST的高压交流-直流转换器在单个芯片内整合了先进的脉宽调制（PWM）控制器和高压功率MOSFET。

这使其成为输出功率在几瓦到几十瓦范围内的离线开关电源（SMPS）的理想选择。该系列有众多产品供选择，您可以为最流行的拓扑结构选择最佳搭配，包括准谐振、反激和降压配置（隔离式或非隔离式应用），多保护特性可确保满足最严苛的可靠性要求。所需外部元件数量也可达到最低，从而最大限度地降低成本。

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。

带有独特的零功率模式的新型VIPer0P

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 V_AC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。
