Procurement Notes
Verify component status as discontinued or not recommended for new designs through official manufacturer channels. Confirm RoHS compliance and REACH status prior to integration. Ensure compatibility with existing HTSOP-J8 footprints if substituting from earlier revisions. Consult datasheets for thermal requirements and operating temperature limits.
Selection Notes
Select this component for designs requiring integrated power MOSFETs in a compact form factor. Consider the 300kHz switching frequency for balancing efficiency and external component size. Verify that the 1.5A output current meets load requirements. Check for availability of compatible evaluation boards for initial validation.
Part Context
This part belongs to Rohm's family of flexible step-down switching regulators. It shares architectural similarities with other models like the BD9673EFJ, featuring built-in power MOSFETs. The series targets industrial and general-purpose power supply applications requiring efficient voltage regulation.
Replacement Considerations
