Abstract
In this paper some principles of power feeding are discussed. For power supply of digital telphone sets the use of a DC/DC converter is a reasonable solution. With the implementation of the DC/DC converter into the terminal some problems must be solved like noise problems, decoupling problems and stabilized operation. A realization of a DC/DC converter is shown which has a good efficiency with loads from 10 mW to 1W. The converter can be used for the S -interface as well as for the U-interface in PABX applications.
