Overview
Si9117 Vishay Siliconix High-Frequency Converter for Telecom Applications FEATURES D D D D On-board high-voltage, 1-W Switching FET Switching Frequencies of Up to 1 MHz Synchronization Capability Easily Compensated Current-Mode Operation D D D D Operates with Input Voltages Up to 200 V 1.
8-MHz Error Amplifier Soft-Start Latched SHUTDOWN DESCRIPTION The Si9117 high-efficiency converter for telecom systems running off 48 V is ideal for emerging applications such as interactive video (IV) set-top boxes and microcell base stations, such as those used for Personal Communications Systems (PCS).
IV set-top boxes and microcell base stations typically require less than 15 W of power and have access to the analog telephone line power.
Both IV set-top boxes and microcell base stations process extremely low-level, modulated analog signals (on the order of mVs), making the frequency and energy content of radiated and conducted noise a major issue.
These application circuits are also constrained i...
