Texas Instruments

Published Date: 04/09/2003

Description

The boost converter is modified to provide bipolar 12-V outputs from 5-V supply. Using the UCC3803 to control the basic boost converter building block the -12-V outputs are generated using a coupled inductor and a flying capacitor. Output voltage regulation and efficiencies are compared and presented.
