NCV78763MW1AR2G

Overview

The NCV78763MW1AR2G is an automotive-grade LED lighting driver IC designed for power ballast and dual LED driver applications. It integrates a boost converter and two synchronous buck regulators, supporting output currents up to 1.6 A per channel. The device operates within a supply voltage range of 4 V to 40 V and features a switching frequency of 8 MHz. Packaged in a QFN-32 format, it supports PWM dimming and includes short circuit and thermal protection mechanisms. Certified to AEC-Q100 standards, it functions reliably between -40°C and +150°C.

Feature Summary

• Integrates a single boost stage with two independent synchronous buck channels for flexible LED configuration
• Supports high-frequency PWM dimming for precise brightness control in automotive lighting systems
• Includes built-in short circuit and thermal protection to ensure operational safety under fault conditions

Applications

• Automotive front lighting systems requiring combined power ballast and LED drive capabilities
• Dual-channel LED headlamp modules utilizing mixed boost and buck topologies
• High-efficiency automotive illumination solutions compliant with AEC-Q100 reliability standards

Procurement Notes

Verify the specific suffix 'MW1A' against official onsemi documentation to confirm pinout and functional variations relative to other NCV78763 variants. Confirm current availability status as distribution channels may list this part as discontinued or limited stock. Ensure compatibility with required PCB footprint for the QFN-32 package during procurement planning.

Selection Notes

Select this component when designing automotive lighting circuits that require both boost conversion for ballasts and buck regulation for LEDs within a single chip. Consider the 40 V maximum input rating and 1.6 A output capability for appropriate load matching. Evaluate the QFN-32 thermal performance requirements against the intended operating temperature range of -40°C to +150°C.

Part Context

This part belongs to the NCV78763 family of intelligent power drivers from onsemi, tailored for automotive exterior lighting. The series provides integrated solutions for complex lighting architectures, combining multiple power stages to reduce component count and board space. It addresses the demand for high-efficiency, compact, and reliable lighting controllers in modern vehicle designs.

Replacement Considerations

Check for NCV78763DQ9R2G if an SSOP-36 package is acceptable instead of QFN-32. Verify NCV78763MW0R2G for potential pin-compatible alternatives within the same package family. Consult official substitution guides for any functional differences in suffix codes.
