NCV898032D1R2G

Overview

The NCV898032D1R2G is an automotive-grade, non-synchronous boost controller manufactured by onsemi. It operates at a fixed switching frequency of 2 MHz and is designed for step-up voltage conversion applications. The device features integrated protection mechanisms including overvoltage, undervoltage lockout, and thermal shutdown to ensure reliable operation in harsh automotive environments. It utilizes a compact DFN package suitable for space-constrained designs.

Feature Summary

• Automotive qualified to AEC-Q100 standards for high reliability
• Fixed 2 MHz switching frequency enables small external component size
• Integrated overvoltage and thermal protection circuits
• Non-synchronous topology optimized for cost-effective boost applications

Applications

• Automotive infotainment systems
• LED illumination drivers
• Sensor power supply conditioning
• General automotive electronics requiring boosted voltage rails

Procurement Notes

Verify the specific suffix D1R2G against the official datasheet to confirm pinout and packaging details. Confirm AEC-Q100 qualification status if required for your specific automotive tier. Check for any recent Product Change Notifications regarding manufacturing site or material composition changes before finalizing procurement.

Selection Notes

Select this component when a fixed-frequency boost solution is required for automotive applications. The 2 MHz frequency allows for smaller inductors and capacitors compared to lower frequency alternatives. Ensure input voltage ranges align with the controller's operating specifications and that thermal management strategies accommodate the non-synchronous topology losses.

Part Context

This part belongs to the NCV89803x family of automotive power management ICs. It shares functional similarities with the NCV898031 but is specifically configured as a boost controller rather than a SEPIC/Boost variant. The family targets robust performance in demanding vehicle electrical systems.

Replacement Considerations

Direct substitutes include the NCV898031D1R2G for SEPIC/Boost flexibility or other NCV89803x variants within the same package. Verify compatibility with existing PCB footprints and control loop compensation when cross-referencing with competitor boost controllers.
