The FL7740 provides accurate CV regulation in the steady state with differentiated dynamic function to minimize overshoot and undershoot of output voltage in line and load transient condition. Standby power is less than 0.3 W for smart lighting application and power factor is higher than 0.9 even at half load condition when enabling PF optimizer for wide out.
• Wide Universal Input Range (90 VAC ~ 305 VAC)
• Precise CV Regulation in the Steady State: < ±3 %
• CV Regulation in the load Transient: < ±10 %
• Overshoot−Less Fast HV Start Up Time (< 0.2 s)
• Low Standby Power
• PF Higher than 0.9 at High−Line and Half load by PF Optimizer
• Pulse−by−Pulse Current Limit
• Output Short Protection
• Output Over Voltage Protection
• Output Diode Short Protection
• Sensing Resistor Short & Open protection
• Over Load Protection
• These Devices are Pb−Free Devices
Typical Applications
• LED Lighting System
• AC−DC Adapters, TVs, Monitors
• Off Line Appliances.
