    • Evaluation Board
    • BD9G341AEFJ-EVK-101
    • 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.
