NCV78763DQ0AR2G

Overview

The NCV78763DQ0AR2G is a dual-channel LED lighting driver IC designed for automotive applications, featuring integrated boost and buck DC-DC converter topologies. It supports an input voltage range of 4 V to 40 V and delivers up to 1.6 A output current per channel with open-drain outputs. The device operates at a switching frequency of 8 MHz and includes PWM dimming capabilities. Packaged in a 36-SSOP-EP surface-mount format, it functions within a temperature range of -40°C to +150°C and holds AEC-Q100 qualification.

Feature Summary

• Dual-channel architecture supporting independent LED control via boost and buck topologies
• Integrated PWM dimming interface for precise brightness regulation
• Built-in short circuit and thermal protection mechanisms for system reliability

Applications

• Automotive front lighting systems requiring dual-channel drive
• Power ballast circuits for automotive LED illumination
• High-efficiency LED driver designs in automotive environments

Procurement Notes

Verify the specific suffix 'DQ0A' against official onsemi documentation to ensure correct pinout and electrical characteristics, as variations exist within the NCV78763 family. Confirm package type matches the 36-SSOP-EP specification required for your PCB layout. Check current availability status, as some variants may be discontinued or subject to long lead times. Ensure compliance with AEC-Q100 requirements if used in automotive safety-critical applications.

Selection Notes

Select this component when a single IC solution is needed to drive two separate LED channels with distinct voltage requirements using combined boost and buck conversion. It is suitable for designs requiring high efficiency and compact footprint due to the integrated topology. Consider the 36-pin SSOP package constraints and thermal dissipation needs for the operating environment. Verify that the 8 MHz switching frequency aligns with EMI constraints in the target application.

Part Context

This part belongs to the NCV78763 series of dual-channel LED drivers from onsemi, specifically tailored for automotive lighting. Unlike single-channel counterparts such as the NCV78702, this variant provides two independent outputs. It shares the core control logic with other suffixes like NCV78763MW0R2G but differs in package style (SSOP vs QFN) and specific internal configuration parameters defined by the DQ0A designation.

Replacement Considerations

NCV78763DQ9R2G offers similar functionality but utilizes an SSOP-36 package without the explicit EP designation in some listings; verify pin compatibility. NCV78763MW0R2G provides equivalent electrical performance but uses a QFN-32 package, requiring PCB layout adaptation.
