Procurement Notes
Verify the current lifecycle status before procurement, as this component may be marked as Not Recommended for New Designs (NRND). Confirm that the 16-SOP package and specific suffix align with existing board layouts. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity.
Selection Notes
Select this component for applications requiring a single-channel boost topology with integrated power switching. It is suitable for designs needing PWM dimming capabilities and operation from standard battery or system voltages up to 35 V. Consider the thermal performance given the 625 mW power dissipation limit in the SOP-16 package when evaluating thermal management requirements.
Part Context
This part belongs to the ROHM BD948x series of LED lighting driver ICs. These devices are specifically engineered for LCD backlight applications, offering compact solutions through integrated MOSFETs and various packaging options. The series typically supports multiple channels and dimming interfaces to accommodate diverse display sizes and brightness requirements.
Replacement Considerations
Check for direct substitutes within the BD948x family, such as the BD9486F-GE2 or BD9488F-GE2, ensuring pin compatibility and electrical specifications match. Verify if newer revisions or alternative packages from ROHM are available as recommended replacements.
