Description

General part information

BD9E300EFJ-LB(E2) Series

This product guarantees long life cycle in Industrial market. BD9E300EFJ-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 has a high oscillation frequency of 1MHz while using small inductance value. It is a current mode control DC/DC converter and features high-speed transient response. Phase compensation can also be set easily.BD9E300EFJ-LB is also available as a small reel product with 250 packages.→BD9E300EFJ-LBH2We recommendBD9E300UEFJ-LBE2for your new development. It uses different production lines for the purpose of improving production efficiency. Electric characteristics noted in Datasheet does not differ between Production Line.
