1ch Buck Converter Integrated FET
BD9G341AEFJ
1ch Buck Converter Integrated FET
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.

Reference Design / Application Evaluation Kit

- Evaluation Board - BD9G341AEFJ-EVK-101
This EVK is using not BD9G341AEFJ-LB, but BD9G341AEFJ. This evaluation board has been developed for ROHM’s non-synchronous buck DC/DC converter customers evaluating BD9G341AEFJ. While the BD9G341AEFJ accepts a power supply input range of 12V to 76V, and generates output voltages from 1V to Vcc, this evaluation board is setup for the same input voltage range and a fixed output of 5V can be produced.
