  Linear Technology Magazine Circuit Collection, Volume II &mdash AN66
  PDF, 1.1 Mb, Datei veröffentlicht: Aug 1, 1996
  Application Note 66 is a compendium of "power circuits" from the first five years of Linear Technology. This application note contains circuits that can power most any system you can imagine, from desktop computer systems to micropower systems for portable and handheld equipment. Also included here are circuits that provide 300W or more of power factor corrected DC from a universal input. Battery chargers are included, some that charge several battery types, some that are optimized to charge a single type. MOSFET drivers, high side switches and H-bridge driver circuits are also included, as is an article on simple thermal analysis.

  Application Note 66
  August 1996 Linear Technology Magazine Circuit Collection, Volume II
  Power Products
  Richard Markell, Editor
  INTRODUCTION
  Application Note 66 is a compendium of “power circuits”
  from the first five years of Linear Technology. The objective
  is to collect the useful circuits from the magazine into
  several applications notes (another, AN67, will collect
  signal processing circuits into one Application Note) so
  that valuable “gems” will not be lost. This Application Note
  contains circuits that can power most any system you can
  imagine, from desktop computer systems to micropower
  systems for portable and handheld equipment. Also included here are circuits that provide 300W or more of
  power factor corrected DC from a universal input. Battery
  chargers are included, some that charge several battery
  types, some that are optimized to charge a single type.
  MOSFET drivers, high side switches and H-bridge driver
  circuits are also included, as is an article on simple thermal
  analysis. With these introductory remarks, I’ll stand aside
  and let the authors describe their circuits. ARTICLE INDEX

  Mitchell Lee
  The VPP generator circuits shown here cover a range of
  30mA to 240mA with 3.3V or 5V inputs as noted. Table 1
  summarizes these circuits for quick reference.
