Notas de aplicación

  • LT1575 UltraFast Linear Controller Makes Fast Transient Response Power Supplies &mdash AN69
    PDF, 224 Kb, Archivo publicado: sept 5, 1996
    AN69 describes considerations for linear regulators based on the LT1575 UltraFastTM Linear Regulator controller. The LT1575 drives an external MOSFET pass transistor as an overdriven source follower. This configuration results in an extremely high speed regulation loop which minimizes the need for output capacitors. Target applications are state of the art microprocessor core supplies which exhibit large, high speed load transients while having very tight supply voltage tolerance requirements. The application note shows numerous examples of circuit implementations and offers detailed discussions of design considerations.

  • A Monolithic Switching Regulator with 100ВµV Output Noise &mdash AN70
    PDF, 1.7 Mb, Idioma: en, Archivo publicado: oct 1, 1997
    This publication details circuitry and applications considerations for the LT1533 low noise switching regulator. Eleven DC/DC converter circuits are presented, some offering <100µV output noise in a 100MHz bandwidth. Tutorial sections detail low noise DC/DC design, measurement, probing and layout techniques, and magnetics selection.

  • Linear Technology Magazine Circuit Collection, Volume IV &mdash AN84
    PDF, 2.4 Mb, Archivo publicado: abr 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.
