» Product Change Notification
The FL7740 provides accurate CV (Constant Voltage) regulation 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 half load condition when enabling PF optimizer for wide output powerscalability.
Features   Benefits
     
  • Internal start up JFET
 
  • Fast start up and Low standby power consumption
  • Accurate primary side regulation technique
 
  • Low eBOM counts & precise CV regulation
  • Dynamic CV regulation
 
  • Stable operation with under 10% CV regulation in load transient
  • PF optimizer
 
  • Over 0.9 PF even at half load and univesal input condition
Applications   End Products
  • Smart Lighting AC-DC Power
  • Lighting Driver
  • AC-DC Adapters, TVs, Monitors
