- Portable device backlighting units
Procurement Notes
Verify the specific suffix 'R2G' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the automotive-grade variant designation aligns with project reliability standards if applicable. Ensure the SOIC-8 footprint matches the target PCB layout dimensions. Cross-reference the manufacturer datasheet revision history for any recent material or pinout updates prior to final procurement authorization.
Selection Notes
Select this component when a compact, synchronous buck solution is required for driving high-current LEDs. The fixed 250 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.5 A output limit and 40 V input range to ensure compatibility with the target LED string voltage and current requirements. Evaluate thermal performance within the SOIC-8 package constraints for the intended enclosure environment.
Part Context
This part belongs to the NCP3066 series of LED driver ICs from onsemi. It is functionally related to the NCV3066DR2G, which shares similar electrical characteristics but may differ in automotive qualification status. The DR2G suffix indicates the specific reel packaging format. It serves as a dedicated power management solution within the broader PMIC portfolio for lighting applications.
Replacement Considerations
The NCV3066DR2G is a confirmed substitute part number with identical electrical specifications. Verify that the automotive grade requirement is met if the application demands it, as the NCV prefix typically denotes automotive qualification. Ensure pinout compatibility remains unchanged between the NCP and NCV variants before substitution.
