家电

Power Integrations提供了一系列针对主要家电产品应用的高度集成离线式功率转换用高压IC。每个IC都在单个芯片上集成了一个≥700 V的功率MOSFET、控制电路及保护电路。它所拥有的产品特色包括电流限流、提高可靠性且具有自动故障恢复功能的过热关断保护特性、降低电磁干扰的频率调制特性以及显著降低待机能耗的EcoSmart®技术。

偏高及不稳定电源电压   

高品质家电和其他消费电子产品要求在电网不稳定地区、时常遭受雷击的热带地区或者经常发生高能振荡波和浪涌的地区应留出更高的电压裕量。例如,致力于打开印度高品质消费类产品新兴市场的OEM厂商,如果不对产品留出此裕量,就会不断遭遇电气损坏问题,必须对退货产品进行维修或更换。

Power Integrations现可提供集成900 V初级MOSFET的全套离线式开关电源IC,这些产品不仅能提供低成本且有效的保护,同时还可大幅降低运营及产品支持成本。

  • LinkSwitch-TN2 适用元件数极少的降压转换器
  • LinkSwitch-XT2 适用高达 8 W 隔离或非隔离反激式转换器
  • InnoSwitch3-EP 适用高达 85 W 高功率隔离反激式转换器

这些高度集成的900 V器件可帮助设计工程师实现全球通用的电源,满足全球各地用户的可靠性预期。它们还可以取代现有电源板设计中相应的725 V开关器件,无需修改设计即可支持更高电压。

InnoSwitch3-EP系列的新成员采用900 V氮化镓(GaN)技术,提供高达100 W的功率输出,效率超过93%,并在空间受限的应用中消除了散热器的需要。PI专有的PowiGaN技术提供了实现900V额定值所需的可靠性和坚固性,同时提高了功率和效率,为电压高或不稳定的地区提供了更宽的安全边际。"
