Description
AN732 Vishay Siliconix Designing A High-Voltage Non-Isolated Buck-Boost Converter with the Si9121DY Nitin Kalje INTRODUCTION The Si9121DY is a non-i.
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 availableApplications
* including digital phones and ISDN power supplies. A non-isolated buck-boost design with the Si9121 eliminates the need for an expensive transformer, while its integrated low on-resistance MOSFET driver, floating feedback error amplifier, fixed-frequency oscillator, output voltage sensing resistor diAN732 Distributors
