NCV97310MW33R2G

Overview

The NCV97310MW33R2G is an automotive-grade Power Management Unit (PMU) from onsemi, designed for battery-connected applications. It integrates three synchronous buck regulators with a fixed 3.3V output voltage, operating within a range of 3.23V to 3.37V. The device supports an input supply voltage between 4.5V and 36V. It features a switching frequency of 2MHz to 2.6MHz and is housed in a 32-QFN (5x5mm) package. Certified to AEC-Q100 standards, it ensures reliable operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates three synchronous buck regulators for efficient multi-rail power distribution
• Automotive qualification compliant with AEC-Q100 standards for reliability
• Optimized for low quiescent current in battery-connected systems

Applications

• Automotive infotainment systems
• Telematics control units
• Body electronics modules

Procurement Notes

Verify the specific suffix 'R2G' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications. Ensure compatibility with AEC-Q100 requirements for your target automotive application. Cross-reference the part number with official obsolescence notices or product change notifications to confirm current availability status before finalizing procurement plans.

Selection Notes

Select this component when a compact solution for multiple regulated outputs is required in space-constrained automotive environments. The integrated nature reduces external component count compared to discrete regulator designs. Consider the 3.3V fixed output constraint and ensure it aligns with downstream load requirements without needing adjustable regulation for these specific rails.

Part Context

This part belongs to the NCV97310A series of specialized PMICs. It complements other variants like the NCV97311 by offering a simplified three-buck configuration. The series targets high-volume automotive manufacturing where board space and power efficiency are critical design constraints for modern vehicle electronic architectures.

Replacement Considerations

The NCV97311MW33AR2G is listed as a similar alternative. Verify if the additional LDO outputs in the NCV97311 variant are necessary for your design, as the NCV97310 focuses solely on buck regulation. Check pin-to-pin compatibility and thermal performance differences before substitution.
