NCV78763MW4R2G

Overview

The NCV78763MW4R2G is an automotive-grade LED lighting driver IC designed for power ballast and dual LED applications. It integrates a Boost and Buck topology with two output channels, each capable of delivering up to 1.6 A. The device operates within a supply voltage range of 4 V to 40 V and supports a switching frequency of 8 MHz. Packaged in a QFN-32 format, it meets AEC-Q100 qualification standards and functions reliably across temperatures from -40°C to +150°C.

Feature Summary

• Integrates dual-channel high-efficiency boost and buck converters for flexible LED configuration
• Includes PWM dimming capability alongside short circuit and thermal protection mechanisms

Applications

• Automotive front lighting systems
• LED power ballast circuits
• Dual channel LED driver architectures

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix matches the required package variant. Request official datasheets and quality certificates to ensure compliance with automotive standards before integration into final designs.

Selection Notes

Select this model when designing automotive lighting requiring combined boost and buck topologies. Ensure input voltage ranges between 4 V and 40 V align with system requirements. Verify that the QFN-32 package fits the PCB layout constraints and thermal management strategy.

Part Context

This component belongs to the NCV78763 series of intelligent power drivers. It shares functional similarities with other automotive LED controllers but is distinct due to its specific dual-channel boost-buck architecture and 1.6 A current rating. It serves as a specialized solution for complex headlight modules.
