BD9G201UEFJ-M
1ch Buck Converter
BD9G201UEFJ-M 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.
This IC uses different production line against series model BD9G201EFJ-M for the purpose of improving production efficiency. We recommend using this IC for your new development. Electric characteristics noted in Datasheet does not differ between Production Line. In addition, the data of BD9G201EFJ-M is disclosed for documents and design models unless otherwise specified.

Reference Design / Application Evaluation Kit
-
- Evaluation Board - BD9G201EFJ-EVK-001
This EVK is using BD9G201EFJ-M instead of BD9G201UEFJ-M, BD9G201UEFJ-LB, or BD9G201EFJ-LB. This EVK has been developed for ROHM’s non-synchronous buck DC/DC converter customers evaluating BD9G201EFJ-M. While the BD9G201EFJ-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.
