  Power Supply Recommendations for DVD Receivers
  PDF, 153 Kb, File published: May 4, 2005
  Selecting the optimal power supply for a non feed back digital amplifier can bechallenging. Music is dynamic, so the power consumption is changing dramatically,from almost zero to maximum within a few ms.Designing the power supply so powerful that it can deliver the total amplifier outputpower continuously is too costly and usually unnecessary.Designing the power supply too small gives p
