AN732 Designing A High-Voltage Non-Isolated Buck-Boost Converter with the Si9121DY

AN732 Vishay Siliconix Designing A High-Voltage Non-Isolated Buck-Boost Converter with the Si9121DY Nitin Kalje INTRODUCTION The Si9121DY is a non-isolated buck-boost converter IC, operating from a wide input voltage range of 10 to 60 V with minimal external components. This polarity inverter converts 48 V to +5 V or +3.3 V, making it suitable for applications including digital phones and ISDN power supplies. A non-isolated buck-boost design with the Si9121 eliminate.

AN732 Features

* include the under-voltage lock out, programmable soft start, pulse by pulse current limit, hiccup mode with negligible power delivery and dissipation during continuous short circuit conditions, automatic recovery from hiccup after fault removal, and over temperature shutdown. The Si9121 is available
