This actually not an add on device but a caracteristic design in the front end of a power supply. If you can get a copy of some hold (2-4 years) Unitrode seminar handbook or Unitrode application notes for their ICs you will get some basic information about these. Also Microlinear web site is providing some info on the subject.
