Overview
The BD9A301MUV-LBE2 is a synchronous buck DC/DC converter from ROHM Semiconductor, designed for industrial applications with guaranteed long-term supply. It features an input voltage range of 2.7V to 5.5V and delivers up to 3A output current. The adjustable output voltage spans from 0.8V to 3.85V. Operating at a switching frequency of 1MHz, it utilizes SLLM™ control for enhanced light-load efficiency. The device is housed in a 16-VQFN (VQFN016V3030) package and supports an operating junction temperature range of -40°C to 125°C.
Feature Summary
- Integrated low on-resistance power MOSFETs for high-efficiency synchronous rectification
- SLLM™ control technology optimizes efficiency during light-load conditions
- Current-mode control architecture ensures fast transient response and simplified phase compensation
- Guaranteed long-term availability specifically targeted at industrial market requirements
Applications
- Industrial equipment power management systems
- Portable devices requiring reduced standby power consumption
- Embedded systems utilizing small inductors enabled by high-frequency operation
Procurement Notes
Verify the specific suffix 'E2' against the manufacturer's latest documentation to confirm compliance with RoHS3 standards and any recent Product Change Notices (PCN). Ensure that the VQFN016V3030 package dimensions align with your PCB footprint design. Confirm thermal performance requirements given the 125°C maximum junction temperature rating. Cross-reference ordering information with authorized distributors to ensure genuine sourcing.
Selection Notes
Select this component when a compact solution is required for single-output buck conversion within a 5.5V input limit. The 1MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. The integrated controller and FET simplify board layout and reduce component count. Consider the SLLM™ feature if the application demands high efficiency under varying load profiles, particularly in light-load scenarios common in battery-powered or energy-efficient industrial sensors.
Part Context
This part belongs to the BD9A300MUV series of synchronous buck converters. It shares architectural similarities with the BD9A300MUV-E2 but offers specific industrial-grade support guarantees. The series is characterized by its integration of power switches and control logic into a single small-footprint package, targeting space-constrained designs in the PMIC category.
Replacement Considerations
The BD9A300MUV-E2 is a related variant within the same family. Verify electrical compatibility and pinout alignment before substitution. No other direct public substitute part numbers are confirmed in the provided documentation.
