DC/DC Flyback

Similar to booster converters in architecture and performance the simple flyback converter topology uses a mutually coupled inductor to store energy when current passes through and releasing the energy when the power is removed. However, the primary winding of the transformer replaces the inductor while the secondary provides the output. In the flyback configuration, the primary and secondary windings are utilized as two separate inductors.

Nexperia value proposition

  • Lower switch losses improve even more the thermal behaviour
  • LFPAK and CFP (both clip-bond package) allow a high-efficiency DC/DC converter solutions, while reducing costs (less heating to dissipate)
  • Standard packages MLPAK33 and MLPAK56 also available 
  • Therefore the possibility to go to higher switching frequency (FSW), which leads to smaller inductances and smaller capacities
  • Best thermal performance thanks to clip-bond package - Rth 3x better than competition - and SiGe diodes that have no thermal runaway
