BD9E303UEFJ-LB(H2)
7.0V～36V輸入、3.0A、內置MOSFET 1ch 同步整流 降壓型DC-DC轉換器
BD9E303UEFJ-LB(H2)
7.0V～36V輸入、3.0A、內置MOSFET 1ch 同步整流 降壓型DC-DC轉換器
該產品是能夠保證向工業設備市場長期供應的產品，而且是非常適用於這些應用領域的產品。
BD9E303EFJ-LB是一款內置低導通電阻功率MOSFET的同步整流降壓型開關穩壓器。該產品支持的輸入電壓範圍很寬(7V～36V)，並且可以生成5.0V等低電壓。由於是電流模式控制的DC-DC轉換器，因此具有高速瞬態響應性能，也很容易進行相位補償設置。
本IC是為提高生產效率而對本系列產品中的BD9E303EFJ-LB變更生產線後形成的型號，在新項目選型時，建議選擇該型號，在技術規格書中的保證特性並沒有差異。此外，由於文檔和設計模型等也沒有差異，因此除非另有說明，ROHM將公開BD9E303EFJ-LB的數據。

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.
