SI9100 General 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 unregulate.
