Application Notes

  • Micropower Circuits for Signal Conditioning &mdash AN23
    PDF, 2.2 Mb, File published: Apr 1, 1987
    Low power operation of electronic apparatus has become increasingly desirable. AN23 describes a variety of low power circuits for transducer signal conditioning. Also included are designs for data converters and switching regulators. Three appended sections discuss guidelines for micropower design, strobed power operation and effects of test equipment on micropower circuits.

  • Some Thoughts on DC-DC Converters &mdash AN29
    PDF, 1.2 Mb, File published: Oct 1, 1988
    This note examines a wide range of DC/DC converter applications. Single inductor, transformer, and switched-capacitor converter designs are shown. Special topics like low noise, high efficiency, low quiescent current, high voltage, and wide-input voltage range converters are covered. Appended sections explain some fundamental properties of different types of converters.

  • Switching Regulator Circuit Collection &mdash AN30
    PDF, 606 Kb, File published: Feb 1, 1989
    Switching regulators are of universal interest. Linear Technology has made a major effort to address this topic. A catalog of circuits has been compiled so that a design engineer can swiftly determine which converter type is best. This catalog serves as a visual index to be browsed through for a specific or general interest.

  • A Monolithic Switching Regulator with 100ВµV Output Noise &mdash AN70
    PDF, 1.7 Mb, Language: en, File published: 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.

  • Current Sources for Fiber Optic Lasers: A Compendium of Pleasant Current Events &mdash AN90
    PDF, 409 Kb, File published: Apr 1, 2002
    A large group of fiber optic lasers are powered by DC current. Laser drive is supplied by a current source with modulation added to the signal. The current source, although conceptually simple, constitutes an extraordinarily tricky design problem. There are a number of practical requirements for a fiber optic current source and failure to consider them can cause laser and/or optical component destruction. This application note describes ten laser current source circuits with a range of capabilities. High and low current types are presented, along with designs for grounded anode, cathode or floating operation. Each circuit also includes laser protection features. Appended sections cover laser load simulation and current source noise measurement techniques.
