Application Notes

  • U-164 The UCC3884 Frequency Foldback Pulse Width Modulator
    PDF, 679 Kb, File published: Sep 5, 1999
    This application note discusses the UCC3884 frequency foldback peak-current-mode controller. The UCC3884 solves the current-tail problem often seen in high-frequency converters under overload fault conditions. Intended primarily for single-ended converters, other features such as a maximum duty-cycle clamp and an accurate volt-second clamp are also included. The block diagram and the main features
