  Less Than Half the Price – Design Note 347
  Goran Perica
  Introduction
  Prefabricated power modules offer a simple but expensive solution to the complicated problem of efficiently
  converting high distribution voltages to the isolated low
  voltages required by digital ICs. Build-your-own solutions are much cheaper, but time constraints may drive
  even seasoned power supply designers to the power
  module shelf. The LT®1952 changes that. It simplifies
  the design of a high performance synchronous single
  switch forward converter enough to make it a feasible
  and straightforward cost-cutting alternative to a power
  module.
  A synchronous forward converter is a good choice for
  output voltages in the 1.2V to 26V range. In the forward
  converter family, among the several topologies that can
  achieve high efficiency, the single-switch topology is
  the most cost effective. It requires the least number of
  VL
  47k INPUT
  36V TO 75V power MOSFETs and associated components. Until now,
  though, the single-switch forward converter required
  very complex PWM control circuitry, relegating it to …
