BD9A301MUV-EVK-001: 1.8V @ 3A, 2.7 ~ 5.5V in

Summary

The BD9A301MUV-EVK-001 Evaluation board delivers an output 1.8 volts from an input 2.7 to 5.5 volts 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.
