  A Comparison Between the BiCMOS UCC3895 Phase Shift Controller and the UC3875
  PDF, 21 Kb, Archivo publicado: feb 22, 2001
  This application report compares the BiCMOS UCC3895 to its bipolar predecessors, the UC3875/6/7/8 family and the UC3879 controller. All of these integrated circuits provide the control and drive signals needed to implement a full-bridge converter using phase-shifted control. The UCC3895 represents the latest offering in the Texas Instruments line of phase-shift controllers, incorporating a feature

  DN-63 The Current-Doubler Rectifier: An Alternative Rectification Technique
  PDF, 81 Kb, Archivo publicado: enero 12, 2001
  The UC3875, UC3879, and UC3895 families of ICs control a bridge power stage by phase-shifting the switching of one half-bridge with respect to the other. This method allows constant-frequency pulse-width modulation in combination with resonant, zero-voltage switching for high efficiency performance. These ICs can be configured to provide control in either voltage mode or current mode operation, wi

  Synchronous Rectifiers of a Current Doubler
  PDF, 207 Kb, Archivo publicado: feb 27, 2003
  Driving a current doubler synchronous rectification output stage can be a very complex task, especially for a phase shifted full bridge topology. However, using the A and B outputs of the UCC3895 along with the UCC37324 dual 4-A MOSFET driver, direct PWM control of a synchronous rectifier current doubler output stage achieves. This technique provides the proper gating and timing signals necessary
