Procurement Notes
Verify the specific suffix R2G against official onsemi documentation to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints and thermal management designs. Confirm that the AEC-Q100 qualification meets the target automotive grade requirements. Cross-reference the datasheet revision date to ensure access to the latest electrical characteristics and pinout definitions before finalizing procurement orders.
Selection Notes
Select this component for applications requiring dual-channel buck conversion with integrated sensing. The 1.6 A output capability suits medium-power LED arrays. Verify input voltage stability within the 3.05 V to 3.6 V window. Consider the QFNW-24 package for thermal performance in compact automotive enclosures. Ensure the design accommodates the 10 MHz switching frequency constraints for EMI management.
Part Context
This part belongs to the NCV78723 family of high-efficiency dual LED drivers. It shares core architecture with variants like NCV78723MW2R2G but differs in packaging or specific configuration details defined by the suffix. The family targets robust automotive lighting solutions requiring high reliability and precise current control under varying thermal conditions.
Replacement Considerations
NCV78723MW2R2G is a documented variant within the same series. Verify pinout and electrical parameter equivalence before substitution. Check for any changes in package dimensions or thermal characteristics between the MW5 and MW2 suffixes.
