BD9G341EFJ -1ch Buck Converter Integrated FET

The BD9G341EFJ is a buck switching regulator with integrated 150m Ω power MOSFET. Current mode architecture provides fast transient response and a simple phase compensation setup.

The operating frequency is programmable from 50kHz to 750kHz. Additional protection features are included such as Over Current Protection, Thermal shutdown and Under voltage lockout. The under voltage lockout and hysteresis can be set by external resistor
