NCV78703MW0AR2G

Overview

The NCV78703MW0AR2G is a single-output LED lighting driver IC from onsemi, designed for automotive front lighting applications. It utilizes a boost topology and operates within an input voltage range of 3.1 V to 3.5 V. The device supports a switching frequency between 7 MHz and 13 MHz, delivering an output current of 50 mA with an output voltage range of 3.135 V to 3.465 V. It features PWM dimming control and communicates via SPI. Packaged in a QFNW-24 format, it functions reliably across a temperature range of -45°C to +155°C.

Feature Summary

Integrated multiphase boost controller optimized for high-frequency operation
Supports PWM dimming for precise light intensity control
SPI interface enables digital configuration and monitoring
Designed specifically for automotive-grade reliability

Applications

Automotive front lighting systems
LED headlamp drivers
High-intensity discharge replacement circuits

Procurement Notes

Verify the specific suffix 'R2G' against the latest manufacturer datasheet to confirm packaging and tape-and-reel specifications. Ensure compatibility with automotive qualification standards required for front lighting assemblies. Cross-reference the QFNW-24 package dimensions with your PCB footprint library to prevent assembly errors during production integration.

Selection Notes

Select this component when designing automotive front lighting circuits requiring a single-channel boost driver with digital SPI control. It is suitable for applications demanding high switching frequencies up to 13 MHz and wide operating temperature ranges extending to +155°C. Consider its 50 mA output current capability relative to the target LED load requirements before finalizing the design.

Part Context

This part belongs to the NCV78703 series of LED lighting driver ICs from onsemi. It is distinct from the NCV78702 series, which typically offers dual outputs. The NCV78703 focuses on single-output boost conversion, providing a specialized solution for specific automotive lighting topologies that do not require multi-channel synchronization or independent channel control.
