Overview
The BD1484EFJ-E2 is a switching regulator IC from ROHM Semiconductor, featuring an integrated power switch and FET. It utilizes a buck topology to provide a single adjustable output voltage ranging from 925 mV to 12.6 V with a maximum output current of 3 A. The device operates at a fixed switching frequency of 380 kHz and supports surface-mount installation in an HTSOP-J8 package. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a power switch and FET for compact design
- Supports adjustable output voltage via external feedback
- Fixed 380 kHz switching frequency for stable operation
Applications
- Point-of-load regulation in embedded systems
- Power supply stages for industrial control units
- Voltage conversion for automotive electronics
Procurement Notes
Verify the NRND status before procurement, as this component is not recommended for new designs. Confirm the HTSOP-J8 package compatibility with your PCB footprint. Ensure the input voltage exceeds the minimum required for the desired output. Check RoHS compliance documentation if environmental regulations apply to your manufacturing process.
Selection Notes
Select this part when a single-output buck converter with an integrated switch is required. It suits applications needing up to 3 A output current. Consider the 380 kHz frequency for inductor size trade-offs. Verify that the adjustable output range covers your system requirements. Evaluate thermal performance within the specified operating temperature limits.
Part Context
This component belongs to the BD1484EFJ series of switching regulators. It is categorized under PMIC - Power Management ICs. The manufacturer is ROHM Semiconductor. The part uses an HTSOP-J8 package for surface mount technology. It is distinct from LDO regulators and multi-output converters in the same product family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Consult official ROHM documentation for potential alternatives or updated components.
