- Precision voltage regulation circuits
Procurement Notes
Verify the specific suffix 'H' against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status through current manufacturer documentation. Ensure the QFN-32 package outline dimensions align with your PCB footprint specifications before finalizing procurement.
Selection Notes
Select this component when a precise low voltage synchronous buck solution is required. It is appropriate for designs needing configurable switching frequencies up to 1.2 MHz. Consider its single-output topology and 100% duty cycle capability for efficient step-down conversion within the specified input voltage window.
Part Context
This part belongs to the NCP8123x series of controllers from onsemi. The series includes variants such as the NCP81231MNTXG and NCP81232MNTXG, which offer different channel configurations or additional features like USB-PD support. The NCP81230HMNTWG specifically targets precise low voltage buck control applications.
Replacement Considerations
Potential substitutes within the same family include the NCP81231MNTXG and NCP81232MNTXG. Verify functional compatibility and pinout alignment before substitution. Cross-reference datasheets to ensure equivalent performance metrics and interface requirements are met.
