Application Notes
- Power Conditioning for Notebook and Palmtop Systems &mdash AN51PDF, 260 Kb, File published: 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.Extract from the document - 5V to 3.3V Converters for Microprocessor Systems &mdash AN58PDF, 310 Kb, File published: 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.Extract from the document - A Fourth Generation of LCD Backlight Technology &mdash AN65PDF, 5.9 Mb, File published: Nov 1, 1995
This publication, LTC's fourth effort devoted to LCD backlighting in as many years, treats the subject comprehensively. The text considers lamps, display and layout induced losses, circuitry, efficiency related issues, optimization and measurement techniques. Twelve appended sections cover lamp types, mechanical design, electrical and photometric measurement, layout, circuitry and related topics.Extract from the document
