BD8P250MUF-CE2

Overview

The BD8P250MUF-CE2 is a synchronous rectifying buck DC/DC converter with integrated boost control, manufactured by ROHM Semiconductor. It operates within an input voltage range of 2.7 V to 36 V and delivers up to 2 A output current at a fixed 5 V output. The device features Nano Pulse Control technology and supports switching frequencies up to 2.4 MHz. It includes a shutdown function, PGOOD signal, and light load mode for efficiency optimization. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +125°C in a VQFN24 package.

Feature Summary

• Integrates Quick Buck Booster technology to maintain output voltage during input drops, allowing use as a buck-boost converter with external FETs.
• Employs Nano Pulse Control for high-speed response during buck-boost operation, reducing required output capacitance.
• Includes built-in protection mechanisms and a shutdown pin for power management flexibility.

Applications

• Automotive electronic systems requiring wide input voltage tolerance
• Cold-start scenarios where input voltage fluctuates significantly
• Power supplies needing buck-boost functionality without complex external circuitry

Procurement Notes

Verify the specific suffix CE2 against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compatibility with automotive functional safety requirements if applicable. Cross-reference part numbers such as BD8P250MUF-C for potential aliasing or older revisions. Confirm RoHS compliance status through manufacturer datasheets before integration into production designs.

Selection Notes

Select this component when designing automotive circuits that demand both buck conversion and transient boost capability from a single IC. It is suitable for applications with varying input sources, such as battery-powered systems subject to load dumps or cold cranking conditions. Consider its 2 A capacity and fixed 5 V output for powering microcontrollers or logic circuits directly.

Part Context

This part belongs to ROHM’s automotive-grade PMIC family, specifically designed for robust power management in vehicles. It integrates advanced control techniques like Nano Pulse Control to enhance dynamic performance. The device supports functional safety analysis, making it appropriate for critical automotive subsystems where reliability and voltage stability are paramount.
