Overview
The BD9108FVM-TR is a synchronous buck converter manufactured by ROHM Semiconductor, designed for step-down voltage regulation. It operates within an input voltage range of 2.5 V to 4.5 V and delivers a maximum output current of 600 mA. The device features a fixed switching frequency of 1 MHz and maintains a low quiescent current of 10 uA. It is housed in an MSOP-8 package suitable for surface mount installation. The component supports a shutdown function and functions reliably across an operating temperature range from -25°C to +85°C.
Feature Summary
- Integrates synchronous rectification for efficient step-down conversion
- Supports shutdown mode for power management
- Utilizes a compact MSOP-8 surface-mount package
Applications
- Portable electronic devices requiring efficient power regulation
- Battery-powered systems with limited input voltage ranges
- Embedded circuits needing stable DC-DC conversion
Procurement Notes
Verify the specific suffix and tape-and-reel configuration against official ROHM documentation before procurement. Confirm that the component status aligns with design requirements, as availability may vary. Ensure compatibility with existing PCB footprints and thermal management strategies during the sourcing phase.
Selection Notes
Select this component when a fixed 1 MHz switching frequency and 600 mA output capability are required within a 2.5 V to 4.5 V input window. Consider the MSOP-8 package constraints for space-limited designs. Evaluate thermal performance at maximum load conditions to ensure operation remains within the specified temperature limits.
Part Context
This part belongs to the BD910x series of synchronous buck converters from ROHM. These regulators are engineered for high efficiency in portable applications. The family typically shares similar control architectures and pinouts, facilitating design scalability across different voltage and current requirements within the same product line.
Replacement Considerations
Consult official ROHM substitution guides for verified alternatives. Cross-reference electrical parameters such as input voltage range, output current capacity, and package dimensions to ensure functional equivalence without redesigning the power stage.
