1 / 11 page Vishay Siliconix Si9105 Document Number: 70003 S-70497-Rev. I, 19-Mar-07 www.vishay.com 1 1-W High-Voltage Switchmode Regulator FEATURES • CCITT Compatible • Current-Mode Control • Low Power Consumption (less than 5 mW) • 10 to 120 V Input Range • 200 V, 250 mA MOSFET • Internal Start-Up Circuit • Current-Mode Control • SHUTDOWN and RESET DESCRIPTION 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 °C.
