Key features
  • Quasi-Resonant (QR) topology
  • Primary side regulation of output voltage
  • Direct optocoupler connection for secondary side regulated loop
  • High power factor and low THD in universal and extended range (PF> 0.9 and THD < 5% @ full load and < 10% @ 1/3 load)
  • 800 V fast high-voltage startup
  • Extremely low input power at no-load and standby conditions
  • Integrated input voltage detection for high power factor capabilty, DC rail detection and protection triggering
  • Programmable frequency foldback with valley locking for noise free operation
  • Programmable maximum input power limitation for safety standard compliancy
  • Programmable brownout and input overvoltage protection
  • Latch-free device guarantee by smart Auto Restart Timer (ART)
  • Input pin for remote protection with NTC management (threshold hysteresis and linearization)
