Power Regulation, Conversion and Management
The BD9G341AEFJ is a buck switching regulator with integrated 150mΩ 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 include over-current protection, thermal shutdown and under-voltage lockout. The under-voltage lockout and hysteresis can be set by external resistor.
