  A New Synchronization Circuit for Power Converters (Rev. A)
  PDF, 209 Kb, 修订版: A, 档案已发布: Apr 21, 2010
  The synchronization of multiple PWM and PFC controllers is desirable for many reasons. The most common reason is that it keeps all the noise at one particular frequency and makes it easier to filter. The circuit described changes the slope of the ramp to lock the converter’s switching frequency to an applied signal by a phase locked loop turning it into a voltage controlled oscillator.

  Accurate PWM Duty Cycle Clamp
  PDF, 58 Kb, 档案已发布: Jan 25, 2002
  Power supply applications using current sense transformers require a duty cycle clamp on the pulse width modulator (PWM) to ensure transformer reset. Not all PWMs come with a duty cycle clamp presenting a problem for the power supply designer. This application note shows how to implement a duty cycle clamp by using a simple delay circuit.
