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),
FUNCTIONAL BLOCK DIAGRAM
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 to operate over the industrial temperature range of
? 40 _ C to 85 _ C.
