具有数字参考控制的非隔离式、降压 PFC LED 驱动器

TPS92074 是一款混合功率因数控制器 (PFC)，此控制器针对无需相位调光兼容性的 LED 照明解决方案而进行了优化。 此器件使用一个内部、低功耗、数字控制器来监视转换器已整流交流波形。 此控制器和数模转换器 (DAC) 生成一个已同步三角基准来调节输出电流。 通过在线路周期上允许 LED 电流的变化，并且保持一个已调节总平均电流，可实现高功率因数解决方案。 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。 TPS92074 还包含一些标 • 取自 PFC 的受控基准\n• 恒定 LED 电流运行\n• 低典型运行电流\n• 过压保护\n• 宽温度运行范围\n• 正在申请专利的数字架构\n• 提供 8 引脚小外形尺寸集成电路 (SOIC) 封装和 6 引脚薄小外形晶体管封装 (TSOT);
