DESCRIPTION
The Si9102 high-voltage switchmode regulator is a monolithic
BiC/DMOS integrated circuit which contains most of the
components necessary to implement a high-efficiency
dc-to-dc 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 Si9102 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.
