BD9A301MUV-EVK-001

评估板, 降压DC/DC 转换器, 2.7V-5.5V输入, 3.0A 输出电流

The from ROHM is a step-down DC/DC converter BD9A301MUV-LB evaluation board. The BD9A301MUV-LB is an integrated MOSFET single synchronous buck DC/DC converter. This evaluation board delivers an output 1.8V from an input 2.7V to 5.5V using BD9A301MUV-LB, a synchronous rectification step-down DC/DC converter integrated circuit with output current rating of maximum 3A. It offers high efficiency in all load ranges by equipping the efficiency improvement function in light-load. 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.
