Notas de aplicación
- LT1070 Design Manual &mdash AN19PDF, 656 Kb, Idioma: en, Archivo publicado: jun 1, 1986, Páginas: 80
Application Note 19. This design manual is an extensive discussion of all standard switching configurations for the LT1070; including buck, boost, flyback, forward, inverting and "Cuk." The manual includes comprehensive information on the LT1070, the external components used with it, and complete formulas for calculating component values.Extracto del documento - Switching Regulators for Poets: A Gentle Guide for the Trepidatious &mdash AN25PDF, 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.Extracto del documento - Some Thoughts on DC-DC Converters &mdash AN29PDF, 1.2 Mb, Archivo publicado: 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.Extracto del documento - Switching Regulator Circuit Collection &mdash AN30PDF, 606 Kb, Archivo publicado: 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.Extracto del documento - Linear Circuits for Digital Systems &mdash AN31PDF, 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 AN46PDF, 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.
