LM25010Q0MH/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25010Q0MH/NOPB is an automotive-grade synchronous buck switching regulator designed for high-voltage applications. It features a wide input voltage range of 6V to 42V and delivers up to 1A output current. The device supports adjustable switching frequencies from 100kHz to 1MHz, allowing optimization for size and efficiency. It includes integrated soft-start, frequency synchronization, and comprehensive protection features such as overcurrent, thermal shutdown, and undervoltage lockout. Qualified to AEC-Q100 standards, it operates reliably within a temperature range of -40°C to +150°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Automotive-grade reliability with AEC-Q100 qualification for harsh environment operation
• Wide input voltage capability supporting direct connection to bus systems
• Integrated synchronous rectification for improved efficiency and reduced external component count
• Frequency synchronization pin allows multiple regulators to operate in phase or spread spectrum

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in automotive infotainment and instrument clusters
• Power distribution units (PDUs) and smart junction boxes
• Battery management systems requiring isolated or non-isolated DC-DC conversion
• Industrial control modules operating on 12V or 24V automotive buses

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q0MH' matches the required package and temperature grade. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Cross-reference the datasheet revision date to confirm compatibility with your design specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust, single-output synchronous buck solution is needed for automotive environments. It is suitable for designs requiring input voltages up to 42V with moderate current demands around 1A. Consider the HTSSOP-14 package for space-constrained PCB layouts. Evaluate the need for frequency synchronization if multiple converters are present in the system to minimize EMI interference.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM25010 family of synchronous buck regulators from Texas Instruments. The 'Q' prefix denotes automotive qualification, while '0MH' specifies the HTSSOP-14 package and temperature range. The 'NOPB' suffix confirms environmental compliance. It is distinct from the non-automotive LM25010 and other variants like the LM25013 which may have different current ratings or packages.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include the LM25010MH/NOPB for non-automotive applications, though automotive qualification will be lost. For higher current needs, consider the LM25013 series. Verify pin-to-pin compatibility and electrical parameter overlaps before replacing. Always check the latest datasheets for any obsolescence notices or recommended upgrades.
