Overview
The BD95500MUV-E2 is a synchronous buck converter from ROHM Semiconductor, designed for single-output applications. It operates with an input voltage range of 3 V to 20 V and delivers a maximum output current of 6 A. The adjustable output voltage spans from 700 mV to 5 V. Key electrical parameters include a quiescent current of 10 uA and a programmable switching frequency between 200 kHz and 1 MHz. The device functions within a temperature range of -10°C to +100°C and utilizes a VQFNV6060-EP-40 surface-mount package.
Feature Summary
- Integrates low on-resistance N-channel MOSFETs and a DC/DC controller within a single compact package.
- Features built-in protection circuits for overheat, low input, overcurrent, output overvoltage, and undervoltage conditions.
- Supports selectable light load mode and continuous mode operation for optimized efficiency across varying loads.
Applications
- Portable electronic devices requiring efficient power conversion
- Industrial control systems utilizing wide input voltage ranges
- Battery-powered equipment needing extended runtime through low quiescent current
Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND) before initiating any new product development projects. Confirm that the specific E2 suffix aligns with required environmental compliance standards. Ensure compatibility with the VQFNV6060-EP-40 footprint during PCB layout finalization. Review the official datasheet for updated thermal dissipation requirements associated with the 6 A output capability.
Selection Notes
Select this component when a high-current synchronous buck solution is required within a 3 V to 20 V input window. The integrated FET design reduces external component count compared to discrete solutions. Consider the programmable frequency range for noise management in sensitive analog circuits. Evaluate the thermal performance in the VQFN package against the expected ambient operating conditions.
Part Context
This part belongs to the BD9x500 series of power management ICs from ROHM Semiconductor. It is categorized under Switching Voltage Regulators and specifically functions as a Synchronous Buck Converter. The device is classified within PMIC (Power Management Integrated Circuit) subcategories, targeting applications requiring efficient step-down voltage regulation with integrated power switches.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. The manufacturer indicates this component is not recommended for new designs, suggesting potential obsolescence risks. Engineers should consult official ROHM resources or authorized distributors for current alternative recommendations compatible with the VQFNV6060-EP-40 package.
