The Si9108 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
specifications.
under
the
CCITT
I.430
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 Si9108 is available in 16-pin wide-body SOIC, 14-pin
plastic DIP, and 20-pin PLCC packages, and is specified over
the industrial, D suffix (-40 to 85
°
C) temperature range.
