Overview
The BD9E301UEFJ-LBH2 is a synchronous buck converter IC from ROHM Semiconductor, designed for efficient DC-DC step-down applications. It features an integrated power MOSFET and operates within a wide input voltage range of 7V to 36V. The device delivers a maximum output current of 2.5A with an adjustable output voltage ranging from 1V to 25.2V. It utilizes current-mode control for fast transient response and supports switching frequencies up to 1MHz. The component is housed in an 8-pin HTSOP-J package with an exposed pad, ensuring reliable surface-mount installation.
Feature Summary
- Integrates high-side and low-side power MOSFETs for compact design
- Employs current-mode control architecture for rapid load transient response
- Supports external clock synchronization for noise management
- Includes comprehensive protection mechanisms such as over-current and thermal shutdown
Applications
- Industrial equipment power supplies
- Telecommunication devices
- Home appliances
- USB charger circuits
Procurement Notes
Verify the specific suffix LH2 against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Ensure the ordering information matches the exact RoHS compliance status and packaging type required for your production line. Cross-reference the part number with authorized distributors to avoid counterfeit components and confirm availability.
Selection Notes
Select this component when a wide input voltage range up to 36V is required alongside a 2.5A output capability. It is suitable for designs prioritizing high efficiency and fast transient response due to its current-mode control topology. Consider the HTSOP-J package size and thermal requirements for PCB layout planning. Evaluate the need for external clock synchronization if EMI constraints are critical.
Part Context
This part belongs to the BD9E301EFJ series of synchronous buck converters. It shares functional similarities with other members like BD9E300EFJ and BD9E302EFJ but differs in output current ratings and specific feature sets. The UE variant indicates a specific manufacturing lot or revision within the broader product family.
Replacement Considerations
BD9E301EFJ-LB(E2) is a documented predecessor or equivalent variant within the same series. Verify that the electrical parameters and pin configurations are identical before substitution.
