Application Notes

  • Understanding and Designing an Active Clamp Current Mode Controlled Converter
    PDF, 845 Kb, File published: May 6, 2010
    The UCC2897A Current Mode Active Clamp PWM Controller offers a highly integrated feature set resulting in precision control required for an active clamp forward or flyback converter. The UCC2897A data sheet contains all the design details necessary for accurately programming the device. However, there are significant design considerations and trade-offs unique to the active clamp power stage that
