  • Switching Regulators for Poets: A Gentle Guide for the Trepidatious &mdash AN25
    PDF, 359 Kb, Archivo publicado: sept 2, 1987
    Subtitled "A Gentle Guide for the Trepidatious," this is a tutorial on switching regulator design. The text assumes no switching regulator design experience, contains no equations, and requires no inductor construction to build the circuits described. Designs detailed include flyback, isolated telecom, off-line, and others. Appended sections cover component considerations, measurement techniques and steps involved in developing a working circuit.

  • Linear Circuits for Digital Systems &mdash AN31
    PDF, 1.5 Mb, Archivo publicado: feb 2, 1989
    Subtitled "Some Affable Analogs for Digital Devotees," discusses a number of analog circuits useful in predominantly digital systems. VPP generators for flash memories receive extensive treatment. Other examples include a current loop transmitter, dropout detectors, power management circuits, and clocks.
  • Efficiency and Power Characteristics of Switching Regulator Circuits &mdash AN46
    PDF, 2.6 Mb, Archivo publicado: nov 1, 1991
    Efficiency varies for different DC/DC converters. This application note compares the efficiency characteristics of some of the more popular types. Step-up, step-down, flyback, negative-to-positive, and positive-to-negative are shown. Appended sections discuss how to select the proper aluminum electrolytic capacitor and explain power switch and output diode loss calculations.
