What are the key features of LM22676QMRE-5.0/NOPB?
- AEC-Q100 Grade 1 qualified for automotive applications operating from -40°C to 125°C
- Wide 4.5 V to 42 V input range with fixed 5.0 V / 3 A output suits 12 V and 24 V automotive and industrial bus designs
- Precision enable threshold with 1.2 V hysteresis enables accurate power sequencing and system-level protection
What is LM22676QMRE-5.0/NOPB used for?
LM22676QMRE-5.0/NOPB is designed for automotive body electronics, infotainment systems, and ADAS modules that require a robust 5 V, 3 A supply from a 12 V or 24 V vehicle battery rail. Its AEC-Q100 Grade 1 qualification and -40°C to 125°C operating range meet the stringent reliability requirements of under-hood and instrument-cluster applications. Industrial control panels and building automation equipment operating from 24 V or 48 V DC bus rails also benefit from its high input voltage tolerance and precision enable feature.

Frequently Asked Questions
What is the AEC qualification grade of LM22676QMRE-5.0/NOPB, and what temperature range does it cover?
LM22676QMRE-5.0/NOPB is AEC-Q100 Grade 1 qualified, guaranteeing reliable operation from -40°C to 125°C junction temperature. This makes it suitable for automotive under-hood environments where ambient temperatures can routinely exceed 85°C and vibration and thermal cycling stress components beyond consumer-grade specifications.
How does the 3 A output current of LM22676QMRE-5.0/NOPB serve automotive infotainment power rails?
At a fixed 5.0 V output and 3 A continuous current, LM22676QMRE-5.0/NOPB can simultaneously supply a processor at 1.5 A, a USB port at 0.5 A, and peripheral logic at 1 A, eliminating the need for a second regulator. This consolidation reduces BOM cost and saves approximately 20 mm² of PCB area in compact head-unit designs.
What switching frequency does LM22676QMRE-5.0/NOPB use, and how does it affect output filter component sizing?
The device switches at 500 kHz, allowing the use of a small 10 µH inductor and 47 µF output capacitor to achieve stable 5 V regulation with low ripple. This is roughly half the inductance required at 250 kHz, directly reducing the footprint and cost of the output LC filter in space-constrained automotive PCB layouts.
