Overview
The BD9A600MUV-E2 is a synchronous buck DC-DC converter manufactured by ROHM Semiconductor. It integrates high-side and low-side N-channel MOSFETs to deliver up to 6 A of output current. The device operates with an input voltage range of 2.7 V to 5.5 V and provides an adjustable output voltage from 800 mV to 3.85 V. It features a fixed switching frequency of 1 MHz and a typical quiescent current of 10 uA. The component supports operation within a temperature range of -40°C to +85°C and is housed in a VQFN016V3030 package.
Feature Summary
- Integrates power MOSFETs for compact single-chip solution
- Utilizes SLLM control for improved light-load efficiency
- Includes comprehensive protection mechanisms such as over-current, short-circuit, and thermal shutdown
Applications
- Portable electronic devices requiring low standby power
- Battery-powered equipment needing efficient voltage regulation
- General-purpose point-of-load conversion in consumer electronics
Procurement Notes
Verify the specific suffix E2 indicates RoHS compliance and lead-free status according to official documentation. Confirm the package variant matches the required footprint. Check for any obsolescence notices or recommended design-in alternatives if applicable. Ensure compatibility with intended operating temperatures and electrical loads before finalizing procurement decisions.
Selection Notes
Select this component when a 6 A output current is required within a 2.7 V to 5.5 V input window. It is suitable for applications prioritizing small form factors due to the integrated MOSFETs and 1 MHz switching frequency. Consider the 800 mV minimum output voltage constraint for low-voltage logic supplies. Evaluate thermal performance requirements given the VQFN package size.
Part Context
This part belongs to the BD9A600MUV series of synchronous buck converters. It shares architectural similarities with other members like the BD9A400MUV-E2 and BD9A300MUV-E2, differing primarily in maximum output current capabilities. The series is designed for portable applications requiring high efficiency and minimal external component count.
Replacement Considerations
The BD9A600MUV is the non-RoHS predecessor to the BD9A600MUV-E2. For lower current needs, the BD9A400MUV-E2 (4 A) or BD9A300MUV-E2 (3 A) offer compatible pinouts and specifications.
