The Siliconix SI9108DW is a monolithic BiC/DMOS integrated circuit designed for high-efficiency DC/DC converters, particularly in ISDN terminals up to 3 watts. It operates with a wide input voltage range from 10 V to 120 V and includes a 200 V, 250 mA MOSFET.
Key features include current-mode control, low power consumption (less than 5 mW), and a maximum duty cycle of 99.9%. The device also incorporates an internal start-up circuit and SHUTDOWN and RESET functions. Its low supply current of 0.5 mA max enables designs with up to 60% efficiency at 25 mW, meeting CCITT I.430 specifications.
The SI9108DW is available in 16-pin wide-body SOIC, 14-pin plastic DIP, and 20-pin PLCC packages. It is specified for industrial temperature ranges from -40 °C to 85 °C. This device can be used with a transformer to implement isolated flyback power converter topologies for single or multiple regulated DC outputs.
