应用须知
- Efficiency and Power Characteristics of Switching Regulator Circuits &mdash AN46PDF, 2.6 Mb, 档案已发布: 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.
