AN702 Efficient Isdn Power Converters Using The Si9100

www.DataSheet4U.com AN702 Vishay Siliconix Efficient ISDN Power Converters Using the Si9100 INTRODUCTION One of the latest technology revolutions, an integrated worldwide telecommunications network, will be accompanied by another advance in power conversion technology. The integrated services digital network (ISDN) will allow different forms of information.

Features

of the ISDN power-feeding concept which has been endorsed by the CCITT. ISDN POWER FEEDING Figure 1 is a block diagram of the ISDN basic access configuration. The two-wire transmission line defined at the U-interface provides a 192 k-bits-per-second (bps) digital data A major requirement of these telecom applications (due to the path which connects subscriber equipment to the local need for emergency-mode operation from a high-impedance telephone exchange. Although ISDN permits many new source) is high-efficiency energy conversion at fractional-watt services to be offered, the basic service .
