Description | 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 ... |
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 in a narrow body SO-8 package and allows power dissipation of up to 1.25 W. while the output capacitor supports the load current. Since the current in an inductor cannot change instantaneously, the voltage across it reverses to maintain a constant current when the main switch turns off. The reverse... |
