  DESIGN IDEAS Synchronous, Phase Modulated, Full
  Bridge Converter Targets Isolated High
  by Kurk Mathews
  Power Applications
  Introduction In networking and telecom equipment,
  power supplies provide isolated low
  voltage outputs from the 48V input
  supply rail, with the added requirements of high efficiency (to reduce
  heat dissipation) and low component
  height. These requirements become
  even more difficult to meet with increased power levels, because of the
  corresponding component power dissipation and increased transformer
  size. Simple power supply topologies
  give way to more complex single and
  two-stage approaches that focus on
  transformer and semiconductor utilization.
  One such approach, the phase
  modulated full bridge converter, is a
  popular choice for high power supplies. Unfortunately, until now, there
  has not been a controller that offers
  both the flexibility in timing control
  and features (such as synchronous
  rectifier outputs) to manage a variety …
