Abstract
Official abstract text for this publication.
A subscriber line interface circuit (SLIC) is herein described. In accordance with one aspect of the present proffered solution, the SLIC includes a first interface circuit operably coupled to a first subscriber loop and a second interface circuit operably coupled to a second subscriber loop. The SLIC further includes a power supply circuit that is coupled to the first and second interface circuits to provide first and second output voltages to the respective interface circuits. The power supply circuit includes a switching power converter that is operably supplied with an input voltage and is configured to provide an intermediate voltage signal at an intermediate circuit node. At least a first and a second output branch are connected to the intermediate circuit node. Each output branch includes an output capacitor that is coupled to the intermediate circuit node and that provides an output voltage signal that depends on the intermediate voltage signal. The switching power converter is configured to repeatedly set the signal level of the intermediate voltage signal to a high voltage level for a first time interval and to a low voltage level when the first time interval has elapsed.
