Overview
The NCV78703MW1R2G is a single-chip, high-efficiency boost controller designed for automotive front lighting applications. It supports up to three independent LED channels with a maximum output voltage of 64.8V and an operating frequency of 350kHz. The device features SPI programmability for dynamic parameter adjustment and integrates active input filtering to reduce battery current ripple. Packaged in a 24-QFN (4x4) format, it operates within a junction temperature range of -40°C to 150°C.
Feature Summary
- Integrates active input filtering to minimize battery current ripple
- Supports multi-phase boost configurations for optimized filtering
- Features SPI interface for dynamic system control and programming
Applications
- Automotive front lighting systems
- Smart power ballast designs
- High-current LED string drivers
Procurement Notes
Verify the specific suffix 'R2G' against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Confirm AEC-Q100 qualification status and PPAP capability requirements for your target automotive application tier before finalizing procurement decisions.
Selection Notes
Select this component when designing multi-channel automotive LED systems requiring precise current regulation and reduced external component count. Ensure the design accommodates the 350kHz switching frequency and utilizes the SPI interface for necessary dimming or configuration adjustments during operation.
Part Context
This part belongs to the NCV7870x family of LED driver controllers from onsemi. It shares architectural similarities with the NCV78702 but provides support for three independent output channels instead of two, offering higher flexibility for complex lighting arrays while maintaining similar efficiency and packaging characteristics.
Replacement Considerations
The NCV78702 serves as a related alternative within the same product family, providing identical functionality but limited to two output channels. Verify pinout compatibility and channel count requirements when considering substitution between these variants.
