设计范例开箱 - DER-1038 - 100W超薄LED驱动器，采用750V PowiGaN
该设计展示了InnoSwitch4-QR反激开关IC在超薄100W LED驱动板中的优势，适用于LED灯带和线性灯具。该无散热器设计实现了超过92%的效率，仅使用62个元件，厚度仅为16毫米。它还提供无闪烁性能，并允许在高达55°C的高环境温度下运行。
InnoSwitch4-QR设备将主控制器、750V PowiGaN 开关、FluxLink反馈、SR驱动器和次级控制器集成在一个紧凑的24针低外形封装中。它们使反激电源级设计变得简单，消除了复杂的半桥LLC实现的需求。
前端功率因数校正（PFC）级采用HiperPFS-4设备，在整个交流线路上实现了超过0.95的功率因数和低于10%的总谐波失真（THD）。
