ROHM Product Detail

BD9E303UEFJ-LB(E2)
7.0V~36V输入、3.0A、内置MOSFET 1ch 同步整流 降压型DC-DC转换器

该产品是能够保证向工业设备市场长期供应的产品,而且是非常适用于这些应用领域的产品。BD9E303EFJ-LB是一款内置低导通电阻功率MOSFET的同步整流降压型开关稳压器。
该产品支持的输入电压范围很宽(7V~36V),并且可以生成5.0V等低电压。由于是电流模式控制的DC-DC转换器,因此具有高速瞬态响应性能,也很容易进行相位补偿设置。

BD9E303UEFJ-LB支持250枚卷盘装小批量供应→BD9E303UEFJ-LBH2

本IC是为提高生产效率而对本系列产品中的BD9E303EFJ-LB变更生产线后形成的型号,在新项目选型时,建议选择该型号,在技术规格书中的保证特性并没有差异。此外,由于文档和设计模型等也没有差异,因此除非另有说明,ROHM将公开BD9E303EFJ-LB的数据。

Reference Design / Application Evaluation Kit

 
    • Evaluation Board - BD9E303EFJ-EVK-001
    • This EVK is using not BD9E303UEFJ-LB, but BD9E303EFJ-LB. BD9E303EFJ-EVK-001 Evaluation board delivers an output 5.0 volts from an input 7.0 to 36 volts using BD9E303EFJ-LB, a synchronous rectification step-down 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.
