概览

FLS3247 是一款带功率 MOSFET 的高度集成的 PWM 控制器，具有多个特性可增强低功耗反激转换器的性能。该专利拓扑结构简化了 LED 照明应用的电路设计。LED 照明板采用单级拓扑结构和初级侧调节，以极少数外部组件和最低的成本即可实施；不需要输入降压电容器或反馈电路。为实现良好的功率因数和低 THD，可通过将外部电容器连接至 COMI 来利用恒定导通时间控制。精准恒定电流控制器根据输入电压和输出电压的变化调节精确的输出电流。运行频率与输出电压成比例变化，可保证 DCM 运行，且能效更高，设计更简单。FLS3247 提供开路 LED、短路 LED 和超温保护等保护功能。电流限制电平会自动降低，以在短路 LED 状况下尽可能减少输出电流，保护外部组件。
