Vishay Siliconix
1-W High-Voltage Switchmode Regulator
DESCRIPTION
FEATURES
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.
