  Linear Technology Magazine Circuit Collection, Volume II &mdash AN66
  PDF, 1.1 Мб, Файл опубликован: 1 авг 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.

  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

  Linear Technology Magazine Circuit Collection, Volume IV &mdash AN84
  PDF, 2.4 Мб, Файл опубликован: 1 апр 2000
  Application Note 84 is a collection of "power circuits" from the years 1996 through 1998 as seen in the pages of Linear Technology magazine. This Application Note collects circuits that can output tens of amps to circuits that can operate a handheld device for several years. In addition to a wide variety of traditional power supply circuits (Buck, Boost, Inverting, Flyback, Linear Regulators, etc.) we include circuits for charging batteries, several Power Management circuits as well as circuits that highlight a very low noise switching regulator.

  Power Products
  Richard Markell, Editor
  INTRODUCTION
  Application Note 84 is the fourth in a series that excerpts
  useful circuits from Linear Technology magazine to preserve them for posterity. This application note highlights
  “power” circuits from issue VI:1 (February 1996) through
  issue VIII:4 (November 1998). Another application note
  will feature data conversion, interface and signal processing circuits from the same era. Like its predecessor, AN 66,
  this Application Note includes circuits that can power
  most any system you can imagine, from “server” power
  supplies that generate in excess of 50 amps to micropower systems for portable and handheld equipment.
  Also included are power converters that can be voltage programmed using Intel’s VID code. Charge pump converters, linear regulators and battery charger circuits are
  included here, with Li-Ion batteries receiving extra attention. There are, of course, circuits that cannot be so simply
  categorized. Come browse. I’ll get out of the way and let
  the authors describe their creations.
  Note: Article Titles appear in this application note exactly
  as they originally appeared in Linear Technology magazine. This may result in some inconsistency in the usage
  of terminology. TABLE OF CONTENTS

  250kHz, 1mA I Q Constant Frequency Switcher Tames Portable Systems Power &mdash DN108

  Portable Systems Power – Design Note 108
  Bob Essaff
  DC-to-DC power conversion remains one of the toughest tasks for portable system designers. Dealing with
  various battery technologies and output voltage requirements dictate the need for creative circuit solutions. The
  two circuits discussed are tailored for operation from
  a single lithium-ion (Li-Ion) cell. These new batteries
  are п¬Ѓnding widespread use due to their high energy
  storage capabilities. The п¬Ѓrst circuit has a 3.3V output
  and the second circuit has both 5V and –5V outputs
  for applications requiring dual supplies.
  At the heart of each circuit is the LTВ®1373 current mode
  switching regulator. Guaranteed to operate down to
  2.7V, this part allows the full energy storage capacity
  of a single Li-Ion battery to be used. The LT1373 draws
  only 1mA of quiescent current for high efficiency at
  light loads and has a low resistance 1.5A switch for
  good efficiency at higher loads. Switching at 250kHz
  saves space by reducing the size of the magnetics,
  and the п¬Ѓxed-frequency switching also reduces the
  noise spectrum generated. To avoid sensitive system
  frequencies the part can be externally synchronized
  to a speciп¬Ѓc frequency from 300kHz to 360kHz. The …

  Monolithic DC/DC Converters Break Speed Limits to Shrink Board Space &mdash DN125

  advertisement Monolithic DC/DC Converters Break 1MHz to
  Shrink Board Space – Design Note 125
  Mitchell Lee
  In the never-ending quest for board space, operating
  frequency remains the most important variable in a
  DC/DC converter design. Higher frequency equates
  with smaller coils and capacitors. A new family of fast
  monolithic converters that allows circuit designers to
  reduce the size of their п¬Ѓnished products is now available. Other improvements include quiescent currents
  well below those of slower converters and a new switchdrive technique that reduces dynamic losses by at least
  four fold over previous methods, virtually eliminating
  these losses as a concern in efficiency calculations.
  Table 1 shows the salient features of each member of
  the family. Each is configured as a grounded-switch
  step-up converter, but is equally useful in positive
  and negative high efficiency buck, SEPIC, inverting
  and flyback circuits. The converters are all based
  on the LT В®1372 design, which operates at 500kHz,
  draws 4mA quiescent current and contains a 1.5A,
  0.5О© switch. The LT1371 is designed for higher
  power applications, with a 3A, 0.25О© switch. Supply
  current and operating frequency remain unchanged.
  Reduced quiescent current (1mA) makes the LT1373 …
