BD9E303EFJ-EVK-001

The BD9E303EFJ-EVK-001 from ROHM is an evaluation board for BD9E303EFJ-LB step-down DC/DC converter. The BD9E303EFJ-LB is a synchronous buck switching regulator with built-in power MOSFETs. This evaluation board delivers an output 5V from an input 7 V to 36V using BD9E303EFJ-LB, 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 (3 pin) of the IC.

• Output voltage setting range from VIN x 0.06V to VIN x 0.8V
• Loop bandwidth of 18.2KHz
• Phase margin of 70.8°
• Input ripple voltage of 300mVpp at IO = 3A
• Output ripple voltage of 30mVpp at IO = 3A
• Output rising time of 2.2ms
• Operating frequency of 300KHz
• Maximum efficiency of 91.1% at IO = 1.2A
