Single Stage Power Factor Corrected Isolated Flyback, Converts Offline Voltages to 10.5Vdc @2A


Design files


When input power factor is necessary (like LED lighting, avionics or low THD application as well as the isolation), the single stage PFC Flyback is the best topology. The only drawback of such topology is the 100Hz/120Hz voltage ripple on output.

  • Power factor corrected (always > 0.95 at full load)
  • Good efficiency (83% peak at 230Vac)
  • Compact form factor
  • EN61000-3-2 Class C compliant (LED lighting)
