SI9100 : The Si9100 high-voltage switchmode regulators are monolithic BiC/DMOS integrated circuits which contain most of the components necessary to implement high-efficiency dc-to-dc converters up to 3 watts. They can either be operated from a low-voltage dc supply, or directly from a 10- to 70-V unregulated dc power source. The Si9100 may be used with an appropriate transformer to implement most single-ended isolated power converter topologies (i.e., flyback and forward), or by using a level shift circuit can generate a +5-V or a −5-V non-isolated output from a −48-V source. The Si9100 is available in both standard and lead (Pb)-free 14-pin plastic DIP and 20-pin PLCC packages which are specified t.
SI9104 : The Si9104 high-voltage switchmode regulator is a monolithic BiC/DMOS integrated circuit which contains most of the components necessary to implement a high-efficiency dc-todc converter up to 3 watts. It can either be operated from a low-voltage dc supply, or directly from a 10- to 120-V unregulated dc power source. This device may be used with an appropriate transformer to implement most single-ended isolated power converter topologies (i.e., flyback and forward). The Si9104 is available in a 16-pin wide-body SOIC and is specified over the D suffix (-40 to 85°C) temperature range.

SI9105 : The Si9105 high-voltage switchmode regulator is a monolithic 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 converter with 60% efficiency at 25 mW, therefore meeting the recommended performance under the CCITT I.430 specifications. 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 PLC.
