Si9104 Vishay Siliconix High-Voltage Switchmode Regulator FEATURES • 10- to 120-V Input Range • Current-Mode Control • On-Chip 200-V, 5-Ω MOSFET Switch • SHUTDOWN and RESET • High Efficiency Operation (>80%) • Internal Start-Up Circuit • Internal Oscillator (1 MHz) DESCRIPTION The Si9104 high-voltage switchmode regulator is a monolithic BiC/DMOS integrated circuit which contains most of the components 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 converter topologies (i.e., flyback and forward).
