NCV885301D1R2G

Overview

The NCV885301D1R2G is an automotive-grade, non-synchronous buck switching controller manufactured by onsemi. It operates within a wide input voltage range of 3.1V to 40V and supports adjustable switching frequencies from 100 kHz to 500 kHz. The device delivers a maximum output current of 230 mA with a fixed 8 V output capability. It features a duty cycle up to 93% and includes integrated clock synchronization. Designed for high reliability, it meets AEC-Q100 standards and functions across a junction temperature range of -40°C to +150°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for robust performance in vehicle environments.
• Integrated clock synchronization capability allows for precise timing alignment in multi-phase or synchronized systems.
• Wide operating temperature range ensures stable functionality under extreme thermal conditions typical of automotive applications.

Applications

• Automotive infotainment system power distribution
• Vehicle telematics unit voltage regulation
• ADAS sensor module power management

Procurement Notes

Verify the specific suffix 'D1' against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the SOIC-8 package dimensions align with your PCB footprint. Confirm that the non-synchronous topology suits your efficiency targets, as synchronous alternatives may exist within the same family. Check for any recent PCN notices regarding manufacturing site changes.

Selection Notes

Select this component when an automotive-certified, non-synchronous buck controller is required for low-to-medium current loads. It is suitable for designs needing clock synchronization to reduce EMI through frequency spreading or alignment. Consider the 40V input tolerance for direct battery connection scenarios. Evaluate the 230 mA output limit against peak load demands to ensure adequate headroom without external amplification.

Part Context

This part belongs to the NCV8853 series of automotive buck controllers. It shares the core architecture with variants like the NCV885201 but differs in specific configuration options such as the fixed output voltage setting and duty cycle limits. The series is designed to replace older discrete solutions with integrated protection features.

Replacement Considerations

The NCV885201D1R2G is a related variant within the same product family. Verify if the NCV885201's specific output voltage or duty cycle parameters better suit your application before substituting. Both parts share similar packaging and automotive qualifications.
