节能灯驱动IC

该芯片应用于大功率紧凑型荧光灯。外围电路非常简单，仅需一个启动电阻、一个自举供电二极管、一个馈电电容、两个电源旁路电容、一个采样电阻、两个功率MOS管、一个谐振电感、谐振电容及一个隔直电容。\r\n\r\n 该芯片通过采样电阻采样阴极电流，放大后控制压控振荡器的输出频率，从而稳定输出输出阴极电流，实现恒功率控制。这样就可以实现输入电压变化时保持输出功率恒定。\r\n\r\n 芯片工作包含如下几种工作模式：预热，阴极电流设计为正常时的1.4倍，预热时间为0.75秒；点火频率从预时所处频率一直向低扫频，一直达到最低工作频率或者内部计时结束为止；超功率，电流设置为正常工作时的1.3倍
