DN05072/D, 125W Hi-PF Single Stage LED Driver Design Note

DN05072/D, Single Stage Power converters offer a cost effective way to provide power for LED applications with high input power factor and low THD. The most common CrM or Critical Conduction Mode solutions are typically limited to about 50 watts due to high peak currents characteristic of this approach. A CCM or Continuous Conduction Mode flyback converter offers higher power with reduced peak current while still providing high power factor and very low THD. This Design Note outlines modifying NCL30001 CCM solution described in Application Note AND8470 extending the output power up to 125 watts
