BD95831MUV-E2

Overview

The BD95831MUV-E2 is a single-channel synchronous buck DC/DC converter manufactured by ROHM Semiconductor. It operates with an input voltage range of 7.5 V to 15 V and provides a maximum output current of 3 A. The adjustable output voltage spans from 0.8 V to 5.5 V. The device utilizes H Reg™ ONTIME fixed control mode, enabling fast transient response without phase compensation components. It features a switching frequency setting up to 0.8 MHz and includes integrated N-MOSFETs. Key protection mechanisms include cycle-by-cycle overcurrent protection, thermal shutdown, under-voltage lock-out, short circuit protection, and overvoltage protection.

Feature Summary

• Utilizes H Reg™ ONTIME fixed control mode for high-speed transient response without requiring external phase compensation components.
• Integrates N-MOSFETs for space-saving and efficient synchronous rectification in a compact package.
• Includes comprehensive protection circuits such as cycle-by-cycle overcurrent protection, thermal shutdown, and overvoltage protection with timing lock.

Applications

• Power supply units for digital AV equipment
• Embedded systems requiring stable step-down conversion from 7.5V-15V rails
• Portable devices needing efficient power management within limited board space

Procurement Notes

Verify the specific suffix E2 indicates RoHS compliance and lead-free status as per manufacturer specifications. Confirm the package type is VQFN016V3030 (3.0x3.0 mm) for PCB layout compatibility. Check for any obsolescence notices or lifecycle status changes directly from ROHM Semiconductor documentation before finalizing procurement plans.

Selection Notes

Select this component when an input voltage between 7.5 V and 15 V is available and a maximum load current of 3 A is required. It is suitable for designs prioritizing fast transient response without complex compensation networks. Ensure the application temperature range falls within -20°C to +100°C. Consider alternative models if lower input voltages or higher currents are needed.

Part Context

This part belongs to the BD95831MUV series of synchronous buck converters from ROHM Semiconductor. It is designed for applications demanding high efficiency and compact size. The E2 suffix typically denotes environmental compliance. It serves as a solution for stepping down higher bus voltages to lower logic or peripheral voltages in consumer electronics.
