    • Evaluation Board
    • BD9C301FJ-EVK-001
    • BD9C301FJ-EVK-001 Evaluation board delivers an output 3.3 volts from an input 4.5 to 18 volts using BD9C301FJ, a synchronous rectification stepdown DC/DC converter integrated circuit, with output current rating of maximum 3A. The output voltage can be set by changing the external parts of circuit and the loop-response characteristics also can be adjusted by the phase compensation circuit.
