BD9C301FJ
4.5V～18V 輸入, 3A 同步整流1ch 降壓DC/DC 轉換器
BD9C301FJ是在1個晶片中內建低導通電阻的功率MOSFET的同步整流降壓DC/DC轉換器。
輸入電壓範圍廣，最大可輸出3A的電流。可由較少的外接部件構成，從而降低成本。是電流模式控制DC/DC轉換器，具有高速暫態響應性能，可輕鬆設定相位補償。

- 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.
