DESCRIPTION

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 to operate over the industrial temperature range of

?40 C to 85 C.
