設計範例開箱 - DER-1038 - 100W超薄LED驅動器，採用750V PowiGaN
該設計展示了InnoSwitch4-QR反激開關IC在超薄100W LED驅動板中的優勢，適用於LED燈帶和線性燈具。該無散熱器設計實現了超過92%的效率，僅使用62個元件，厚度僅為16毫米。它還提供無閃爍性能，並允許在高達55°C的高環境溫度下運行。
InnoSwitch4-QR設備將主控制器、750V PowiGaN 開關、FluxLink反饋、SR驅動器和次級控制器集成在一個緊湊的24針低外形封裝中。它們使反激電源級設計變得簡單，消除了複雜的半橋LLC實現的需求。
前端功率因數校正（PFC）級採用HiperPFS-4設備，在整個交流線路上實現了超過0.95的功率因數和低於10%的總諧波失真（THD）。
