BD9B600MUV-E2

Overview

The BD9B600MUV-E2 is a single synchronous buck DC/DC converter manufactured by ROHM Semiconductor. It operates with an input voltage range of 2.7 V to 5.5 V and delivers up to 6 A output current. The device supports adjustable output voltages from 800 mV to 4.4 V. Key electrical specifications include a quiescent current of 10 uA, operating supply current of 45 uA, and a switching frequency range of 1 MHz to 2 MHz. It features a 30 mΩ internal MOSFET and includes shutdown functionality. The component is housed in a VQFNV3030-EP-16 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates high-side and low-side synchronous MOSFETs for efficient power conversion.
• Features programmable switching frequency between 1 MHz and 2 MHz to optimize external component size.
• Includes built-in protection mechanisms such as overcurrent protection and thermal shutdown.
• Supports low standby power consumption with dedicated shutdown control pin.

Applications

• Portable electronic devices requiring efficient step-down regulation.
• Industrial control systems utilizing single-supply architectures.
• Embedded systems needing compact power management solutions.
• Battery-powered equipment demanding extended operational life.

Procurement Notes

Verify the specific suffix E2 indicates RoHS compliance when sourcing. Confirm the VQFNV3030-EP-16 package dimensions match your PCB footprint requirements. Ensure the selected supplier provides official datasheets to validate the 6 A current rating and 30 mΩ Rds(on) parameters. Check that the ordering information aligns with the exact part number BD9B600MUV-E2 to avoid confusion with non-E2 variants or different current ratings within the same family.

Selection Notes

Select this component when a 6 A output capacity is required within a 2.7 V to 5.5 V input window. Consider the VQFNV3030-EP-16 package for applications prioritizing thermal performance and space efficiency. Evaluate the 1 MHz to 2 MHz frequency range against inductor size constraints. Compare against lower-current siblings like the BD9B500MUV-E2 if load demands are below 5 A to potentially reduce cost or board area.

Part Context

This part belongs to the BD9B series of synchronous buck converters from ROHM Semiconductor. It shares architectural similarities with models like the BD9B500MUV-E2 and BD9B400MUV-E2 but distinguishes itself through higher current handling capabilities. The series targets applications requiring robust power delivery in small form factors. All members utilize similar control logic and protection features, differing primarily in integrated MOSFET sizing and maximum output current specifications.

Replacement Considerations

The BD9B600MUV is listed as an alias for this part number. Direct substitutes within the same family include the BD9B500MUV-E2 (5 A) and BD9B400MUV-E2 (4.5 A), provided reduced current capacity is acceptable. Verify package compatibility and thermal requirements when cross-referencing these alternatives.
