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 ...
