BD9E303EFJ-EVK-001: 5V @ 3A, 7 ~ 36V in

Summary

BD9E303EFJ-EVK-001 Evaluation board delivers an output 5.0 volts from an input 7.0 to 36 volts 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.

BD9E303EFJ-LB is a synchronous buck switching regulator with built-in power MOSFETs. It is capable of an output current of up to 3A. It is a current mode control DC/DC converter and features high-speed transient response. Phase compensation can also be set easily.

For other variants please see the BD9E30x family of reference designs and ICs available from Rohm Semiconductor and DigiKey Electronics.It is capable of an output current of up to 2.5A.
