NCV891334MW33R2G

Overview

The NCV891334MW33R2G is an automotive-grade synchronous buck converter from onsemi, designed for high-efficiency DC-DC conversion in demanding environments. It features a wide input voltage range of 3.7V to 36V and delivers a fixed 3.3V output at up to 3A. Operating with a switching frequency of 2MHz, it utilizes a compact 6x6 mm WDFN package with exposed pad for optimized thermal performance and minimal footprint.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability
• Synchronous rectification architecture ensures high efficiency across load ranges
• Integrated protection mechanisms including over-current and thermal shutdown

Applications

• Infotainment system power distribution
• Telematics control unit voltage regulation
• Body control module (BCM) power supplies

Procurement Notes

Verify the complete part number against official onsemi documentation to ensure correct suffix alignment. Confirm that the specific variant matches the required output voltage and packaging configuration for your design implementation.

Selection Notes

Select this component when designing for automotive applications requiring robust voltage regulation under wide input variations. The synchronous design offers superior efficiency compared to non-synchronous alternatives, reducing heat dissipation requirements in space-constrained enclosures.

Part Context

This device belongs to the NCV89133x series of step-down converters. It shares architectural similarities with other members like the NCV891330 but differs in output voltage configuration. The series is characterized by its automotive focus and high integration level suitable for modern vehicle electronics.

Replacement Considerations

Direct substitutes within the same family include NCV891330PD33R2G or NCV891330PD50R2G if output voltage compatibility allows. Verify pinout and thermal characteristics before substitution.
