用于 LED 照明的 AC-DC 功率因数校正 3 步进可调光准谐振初级侧电流模式控制器
Obsolete
概览
NCL30085 是一款 AC-DC 功率因数校正的反激控制器，用于隔离和非隔离降压-升压/SEPIC 恒定电流 LED 驱动器。该控制器以准谐振模式运行，可提供最佳能效。由于新型控制方法，该器件能够严格调节初级侧的恒定 LED 电流。因此无需辅助侧反馈电路、偏置和光耦合器。该器件与极少数量的外部部件进行高度集成。内置了一组丰富的安全保护功能，简化了设计。此控制器集成了 3 步进调光，可使用标准墙壁式开关对 LED 灯泡或泛光灯进行调光。除了与传统 3 相灯类似的 70% 和 25% 步进之外，还包括了一个 5% 电流步进，以支持深度调光应用。
