DESCRIPTION
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
I.430 specifications.
under
the
CCITT
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.
