The BD9E300EFJ-EVK-001 from ROHM is an evaluation board for BD9E300EFJ-LB step-down DC/DC converter. The BD9E300EFJ-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 33V using BD9E300EFJ-LB, a synchronous rectification step-down DC/DC converter integrated circuit with output current rating of maximum 2.5A. 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 0.15V to VIN x 0.7V
• Loop bandwidth of 31.6KHz
• Phase margin of 76.5°
• Input ripple voltage of 100mVpp at IO = 2.5A
• Output ripple voltage of 30mVpp at IO = 2.5A
• Output rising time of 3.5ms
• Operating frequency of 1MHz
• Maximum efficiency of 84.7% at IO = 0.9A
