Application Notes

  • Linear Technology Magazine Circuit Collection, Volume II &mdash AN66
    PDF, 1.1 Mb, File published: 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.

  • Linear Technology Magazine Circuit Collection, Volume IV &mdash AN84
    PDF, 2.4 Mb, File published: Apr 1, 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.
