The BD9G341AEFJ is a buck converter designed for a wide input voltage range of 12V to 76V and can deliver a maximum output current of 3A. It features an integrated 150mOc power MOSFET, which enhances efficiency and reduces the need for external components. The device operates with a programmable frequency between 50kHz and 750kHz, allowing flexibility in design. It includes several protection mechanisms such as Over Current Protection, Thermal Shutdown, and Under Voltage Lockout, which can be configured using external resistors. The operating temperature range is from -40¬8C to 85¬8C, and it is housed in a thermally enhanced HTSOP-J8 package, measuring 4.90mm x 6.00mm x 1.00mm. This product is suitable for applications in industrial distributed power systems and battery-powered devices.
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 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.
