Application Notes

  • UCC28700 5-W USB Flyback Design Review (Rev. C)
    PDF, 466 Kb, Revision: C, File published: Feb 21, 2014
    In USB and isolated low power converter designs quasi resonant and discontinuous conduction mode flyback converter topologies are a popular choice, due to their low parts count and relatively low cost. To reduce the cost even further in these designs TI has developed a quasi-resonant/discontinues current mode flyback controller with primary side control.
