Application Notes
- Basic Calculation of a Boost Converter's Power Stage (Rev. C)PDF, 186 Kb, Revision: C, File published: Jan 8, 2014
This application note gives the equations to calculate the power stage of a boost converter built with an IC with integrated switch and operating in continuous conduction mode. It is not intended to give details on the functionality of a boost converter (see Reference 1) or how to compensate a converter. See the references at the end of this document if more detail is needed. - DN-49 UC2577 Controls SEPIC Converter for Automotive ApplicationsPDF, 61 Kb, File published: Sep 5, 1999
The Single-Ended Primary Inductance Converter (SEPIC) can convert an input voltage to an output voltage that is higher, lower, or equal to the input. Conversion is performed without the use of expensive transformers, making the SEPIC a good choice for low-cost, non-isolated applications. The UC2577 provides the switch and control to take advantage of this topology with a minimum of additional part
