SI9104 Overview
The Si9104 high-voltage switchmode regulator is a monolithic BiC/DMOS integrated circuit which contains most of the ponents necessary to implement a high-efficiency dc-todc 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...
