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.
