BD9E301EFJ-EVK-001: 5V @ 2.5A, 7.2 ~ 36V in

Summary

BD9E301EFJ-EVK-001 Evaluation board delivers an output 5.0 volts from an input 7.2 to 36 volts using BD9E301EFJ-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.

BD9E301EFJ-LB is a synchronous buck switching regulator with built-in power MOSFETs. It is capable of an output current of up to 2.5A. 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.
