Evaluation
Board

 
    • Evaluation Board
    • BD9E101FJ-EVK-001
    • BD9E101FJ-EVK-001 Evaluation board delivers an output 5.0 volts from an input 7.2 to 36 volts using BD9E101FJ-LB, a synchronous rectification step-down DC/DC converter integrated circuit, with output current rating of maximum 1A. 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.
