Reference Design / Application Evaluation Kit

 
    • Evaluation Board - BD9C401EFJ-EVK-001
    • This evaluation board has been developed for ROHM’s synchronous buck DC/DC converter customers evaluating BD9C401EFJ. While accepting a power supply of 4.72-18V, an output of 3.3V can be produced. The IC has internal 65mΩ high-side P-channel MOSFET and 35mΩ low-side N-channel MOSFET and a synchronization frequency is of 500kHz.
