Product Overview

The BD9C301FJ-EVK-001 from ROHM is an evaluation board for BD9C301FJ step-down DC/DC converter. The BD9C301FJ is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This evaluation board delivers an output 3.3V from an input 4.5V to 18V using BD9C301FJ, a synchronous rectification step-down 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. To minimize current consumption during standby mode and normal operation, enable mode can be switched by controlling EN pin (6 pin) of the IC.
  • Output voltage setting range from VIN x 0.125V to VIN x 0.7V
  • Loop bandwidth of 39.8KHz
  • Phase margin of 56.2°
  • Input ripple voltage of 120mVpp at IO = 3A
  • Output ripple voltage of 50mVpp at IO = 3A
  • Output rising time of 1ms
  • Operating frequency of 500KHz
  • Maximum efficiency of 91.4% at IO = 1.2A
