BD9E101FJ-EVK-001

评估板, 单路同步降压DC/DC 转换器,7V-36V输入, 1.0A 输出电流

The from ROHM is an evaluation board for BD9E101FJ-LB step-down DC/DC converter. The BD9E101FJ-LB is a synchronous buck switching regulator with built-in power MOSFETs. This evaluation board delivers an output 5V from an input 7.2V to 36V 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. To minimize current consumption during standby mode and normal operation, enable mode can be switched by controlling EN pin 3 pin of the IC.
