Overview
The BD9E301UEFJ-LBE2 is a single synchronous buck DC/DC converter from ROHM Semiconductor, featuring an integrated MOSFET. It operates with an input voltage range of 7 V to 36 V and provides a positive adjustable output starting from 1 V. The device supports a maximum output current of 2.5 A. It is housed in an 8-SOIC package with a width of 3.90 mm and includes an exposed pad for thermal management.
Feature Summary
- Integrates high-side and low-side power MOSFETs into a single synchronous buck topology
- Provides precise control and monitoring capabilities for optimal system performance
- Supports wide input voltage ranges suitable for various industrial applications
Applications
- Industrial equipment power distribution
- Embedded systems requiring stable regulated voltage
- General-purpose DC/DC conversion in compact form factors
Procurement Notes
Verify the specific suffix LBE2 against the manufacturer's latest datasheet to confirm pinout and thermal specifications. Ensure compatibility with your PCB footprint, particularly regarding the exposed pad connection. Check for any recent lifecycle status changes or alternative recommendations from ROHM before finalizing procurement plans.
Selection Notes
Select this component when a compact solution with integrated power switches is required for buck conversion. It is suitable for designs needing an input range up to 36 V and output currents around 2.5 A. Consider the 8-SOIC package constraints and thermal dissipation requirements associated with the exposed pad design for proper heat management.
Part Context
This part belongs to the BD9E301 series of switching voltage regulators. It is designed as a cost-effective and space-saving solution for converting higher bus voltages to lower logic or peripheral supply levels. The integration of the MOSFETs reduces the external component count compared to discrete solutions.
Replacement Considerations
Consult ROHM documentation for direct replacements within the BD9E30x series. Verify pin-to-pin compatibility if substituting with similar packages like the BD9E301EFJ variant, ensuring electrical parameters match the application requirements.
