Anwendungshinweise

  • Power Conditioning for Notebook and Palmtop Systems &mdash AN51
    PDF, 260 Kb, Datei veröffentlicht: Aug 3, 1992
    Notebook and palmtop systems need a number of voltages developed from a battery. Competitive solutions require small size, high efficiency and light weight. This publication includes circuits for high efficiency 5V and 3.3V switching and linear regulators, back light display drivers and battery chargers. All the circuits are specifically tailored for the requirements outlined above.

  • 5V to 3.3V Converters for Microprocessor Systems &mdash AN58
    PDF, 310 Kb, Datei veröffentlicht: Sep 1, 1993
    Many popular microprocessors operate from 3.3V supplies, yet they are used in systems where the predominate source of power is 5V. AN58 presents a collection of both linear and switching regulator solutions for conversion of 5V to 3.3V at currents ranging from 100mA to 20A. Applications information and a comparison of various bypass capacitor types is included. Most of the designs can be easily modified for other intermediate voltages such as 3.45V, 3.7V, and 4.1V.
