The XC9404 series are LED lighting offline controllers that use PFM(Pulse Frequency Modulation) control and have a Power Factor improvement function. The operating input voltage range is 85VAC to 270VAC, and the current is controlled on the primary side without using a Opto-coupler or secondary side control circuit. Because LED current fluctuations caused by input voltage fluctuations and LED voltage fluctuations can be suppressed, a stable LED lighting power supply is obtained.
XC9404系列是LED照明離線控制器,使用PFM(脈沖頻率調制)控制,具有功率因數改善功能。工作輸入電壓范圍為85VAC至270VAC,電流在一次側控制,無需使用光耦或二次側控制電路。由于輸入電壓波動引起的LED電流波動和LED電壓波動可以得到抑制,因此得到了穩定的LED照明電源。
