Product Overview

The BD9A301MUV-EVK-001 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.
  • Loop band width is 89.1KHz
  • Phase margin is 54.1°
  • Input ripple voltage of 140mVpp at IO = 3A
  • Output ripple voltage of 40mVpp at IO = 3A
  • Output rising time of 5ms
  • Operating frequency of 1MHz
  • Maximum efficiency of 91.8% at IO = 0.7A
  • Connect +ve terminal of power-supply to VIN+ and -ve terminal to GND-terminal with a pair of wires
  • Connect load's +ve terminal to VOUT+ terminal and -ve terminal to GND-terminal with a pair of wires
  • Long time support product for industrial application
