Overview
The BD9751FV-E2 is a dual-channel synchronous step-down switching regulator manufactured by ROHM Semiconductor. It integrates two independent DC/DC converters within a single SSOP-28 package, designed for efficient power management in compact electronic systems. The device supports input voltage ranges typical for such regulators and provides stable output voltages controlled via external feedback networks. As a synchronous rectification type, it offers improved efficiency compared to asynchronous designs. This component is currently marked as obsolete with limited availability.
Feature Summary
- Dual-channel architecture providing two independent synchronous buck converter outputs
- Integrated synchronous rectification for enhanced conversion efficiency
- Compact SSOP-28 surface-mount packaging suitable for space-constrained designs
Applications
- Portable consumer electronics requiring multi-rail power supplies
- Embedded systems needing isolated or separate voltage domains
- Industrial control modules with compact form factor requirements
Procurement Notes
Verify obsolescence status before design finalization. Confirm lead times with authorized distributors as stock is limited. Ensure compatibility with existing PCB footprints for SSOP-28 packages. Review latest datasheet revisions for any pinout or electrical characteristic updates prior to procurement.
Selection Notes
Evaluate thermal performance under maximum load conditions due to dual-channel integration. Verify input voltage range matches system supply rails. Check output current capabilities against load requirements. Consider alternative components if long-term supply stability is critical for the product lifecycle.
Part Context
This part belongs to ROHM's series of integrated power management solutions. It replaces older discrete or single-channel regulator designs by consolidating functionality into a smaller footprint. The E2 suffix typically indicates specific environmental compliance or manufacturing lot variations within the standard BD9751 family.
Replacement Considerations
Direct substitutes may include other dual-channel synchronous buck regulators from ROHM or competitors. Verify pin-to-pin compatibility if replacing on existing boards. Compare efficiency curves and thermal dissipation characteristics carefully.
