SI9105 Description
The Si9105 high-voltage switchmode regulator is a monolithic BiC/DMOS integrated circuit which contains most of the ponents necessary to implement a high-efficiency dc/dc converter in ISDN terminals up to 3 watts. A 0.5-mA max supply current makes possible the design of a dc/dc converter with 60% efficiency at 25 mW, therefore meeting the remended performance under the CCITT I.430 specifications. This device may be...
