Procurement Notes
This component has reached End-of-Life status as per the Product Change Notification dated October 1, 2021. Verify availability through authorized distributors or secondary markets, noting that original manufacturer support may be limited. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage and assembly processes.
Selection Notes
Select this controller for single-phase applications requiring up to 14 A output within a 5 V to 20 V input range. Ensure compatibility with external MOSFETs and inductors for the target current and frequency specifications. Consider the 48-QFN package constraints for thermal management and layout density in high-power density designs.
Part Context
Part of the NCP81109 family of single-phase voltage regulators from onsemi, designed for IMVP-9 and similar processor power standards. The HMNTXG suffix denotes the specific tape-and-reel packaging variant in the 48-QFN form factor, aligning with industry-standard footprint requirements for modern CPU power stages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation due to the product's discontinued status. Evaluate alternative single-phase controllers from onsemi or other manufacturers with compatible pinouts, electrical specifications, and package dimensions.
