具有数字参考控制的非隔离式、相位可调光、降压 PFC LED 驱动器

TPS92075 是一款内置有相位调光解码器的混合功率因数控制器 (PFC)。 此器件使用一个内部、低功耗数字控制器来分析线周期以实现整形和对称。 功率转换器级生成一个模拟电流基准并用它来调节输出电流。 此器件使用控制算法来操纵此模拟基准。 这些算法优化了调光器的兼容性、功率因数和总谐波失真 (THD)。通过使用一个恒定关闭时间控制，这个解决方案实现了低组件数量、高效率并自然提供了开关频率的变化。 这个变化创建了一个仿真展频效应，从而简化了转换器电磁干扰 (EMI) 签名并可使用一个更小的输出滤波器。 TPS92075 还包含一些标准特性：电流限制、过压保护、热关断和 VCC 欠压闭锁，所有这 • 取自 PFC 的受控基准\n• 数字 50/60Hz 同步 \n• 恒定 LED 电流运行\n• 由模拟基准控制实现的调光\n• 过压保护\n• 前缘和后缘调光器兼容性\n• 正在申请专利的数字架构\n• 可提供 8 引脚小外形尺寸集成电路 (SOIC) 封装。将于近期提供 6 引脚薄型小外形晶体管封装 (TSOT) 封装。;
