NCV885201D1R2G

Overview

The NCV885201D1R2G is a buck DC-DC switching controller manufactured by onsemi, designed for automotive applications. It operates within an input voltage range of 3.1V to 40V and supports a switching frequency between 100kHz and 500kHz. The device features a maximum duty cycle of 93% or 100% depending on specific operational conditions and provides a single positive output via a transistor driver stage. It is housed in an 8-SOIC package with a width of 3.90mm and is qualified under AEC-Q100 standards for reliability in harsh environments.

Feature Summary

• Integrated clock synchronization capability for multi-phase or parallel system expansion
• Built-in control features including current limiting, enable functionality, and adjustable frequency control
• Automotive-grade qualification ensuring compliance with AEC-Q100 reliability standards

Applications

• Automotive power supply systems requiring robust buck conversion
• Instrument cluster power distribution networks
• Infotainment system voltage regulation

Procurement Notes

Verify the complete part number including suffixes such as D1R2G to ensure correct packaging and tape-and-reel specifications. Confirm AEC-Q100 certification requirements against specific vehicle manufacturer standards. Check for recent Product Change Notifications regarding manufacturing site changes or material declarations to maintain supply chain continuity and regulatory compliance.

Selection Notes

Select this component when a non-synchronous buck controller with external MOSFETs is required for high-voltage automotive inputs up to 40V. Consider the 8-SOIC package constraints for thermal management and PCB layout. Evaluate the need for clock synchronization if integrating with other converters in the same power domain to minimize electromagnetic interference noise.

Part Context

This device belongs to the NCV8852 family of buck controllers from onsemi, specifically tailored for automotive electronics. The NCV8852 series provides flexible solutions for various power stages, with the NCV885201 variant focusing on standard buck topology control without integrated synchronous rectification.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify pinout compatibility and electrical parameter alignment before replacing.
