Linear Technology Magazine Circuit Collection, Volume II &mdash AN66
PDF, 1.1 Mb, 档案已发布: 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 вЂњpower circuitsвЂќ
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 вЂњgemsвЂќ 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, IвЂ™ll stand aside
and let the authors describe their circuits. ARTICLE INDEX
