BD9G401EFJ-M
1ch Buck Converter Integrated FET
BD9G401EFJ is a buck converter with built-in high side MOSFET. It has an input voltage range of 4.5V to 42V. Current mode architecture provides fast transient response and a simple phase compensation setup. The IC is mainly used as a secondary side power supply: for example, a step-down output of 3.3V/5V can be produced from voltage power supply such as 12V or 24V. In addition, it has a synchronization function with an external CLK that provides noise management.
We recommend BD9G401UEFJ-M for your new development. It uses different production lines for the purpose of improving production efficiency. Electric characteristics noted in Datasheet does not differ between Production Line.

This EVK is using not BD9G401UEFJ-M, but BD9G401EFJ-M. This EVK has been developed for ROHM’s non-synchronous buck DC/DC converter customers evaluating BD9G401EFJ-M. While the BD9G401EFJ-M accepts a power supply input range of 4.5V to 42V, and generates output voltages from 1V to VCC, this EVK is setup for the input voltage range of 10V to 42V and a fixed output of 5V can be produced.
