Si9105 - Vishay Power ICs

Si9105 - Vishay Power ICs SI9105 The SI9105 High-Voltage switchmode Regulator is a mono- lithic BiC/DMOS integrated circuit which contains most of the components necessary to implement a high-efficiency DC/DC converter in ISDN terminals up to 3 watts. A 0.5 mA max supply current makes possible the design of a DC/DC con- verter with 60 % efficiency at 25 mW, therefore meeting the recommended performance under the CCITT I.430 specifi- cations. This device may be used with an appropriate transformer to implement isolated flyback power converter topologies to provide single or multiple regulated dc outputs (i.e., 5 V) The SI9105 is available in both standard and lead (Pb)-free 16-pin wide-body SOIC, 14-pin plastic DIP and 20-pin PLCC packages which are specified to operate over the industrial temperature range of - 40 C to 85 By Vishay Intertechnology
