Application Notes

  • Designing UCC28250 as a Secondary Side Control with a Pre-Bias Condition
    PDF, 395 Kb, File published: Nov 24, 2010
    This application note addresses the considerations for using the UCC28250 as a secondary side controller. With voltage mode control, the UCC28250 can be used in a design that produces smooth turn-on performance with an output pre-bias condition. The design guidelines are summarized from various performance tests and examined particularly on a 100-W, dc-dc half bridge converter. This converter is d
  • Differences Between the UCC28251 and UCC28250 and Evaluation of the UCC28251 in (Rev. A)
    PDF, 36 Kb, Revision: A, File published: Feb 15, 2013
    The UCC28251 is a functional variant of the UCC28250 PWM Controller. While the same basic functionality of the UCC28250 is largely maintained, the UCC28251 is designed to operate at a lower frequency (minimum of 27 kHz when programmed by RT pin) allowing operation in 400-V input DC-to-DC converters in off-line AC-to-DC power supplies, where frequency-dependent high-voltage switching lossesare an
