Product Overview

The BD9E101FJ-EVK-001 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.
  • Output voltage setting range from VIN x 0.0855V to VIN x 0.7V
  • Loop bandwidth of 31.6KHz
  • Phase margin of 77.1°
  • Input ripple voltage of 90mVpp at IO = 1A
  • Output ripple voltage of 60mVpp at IO = 1A
  • Output rising time of 3ms
  • Operating frequency of 570KHz
  • Maximum efficiency of 85.4% at IO = 0.85A
