Overview
The NCP81270DMNTXG is a single-phase synchronous buck voltage regulator from onsemi, designed for computer applications. It operates with a VCC supply range of 4.5V to 21V and supports switching frequencies up to 600kHz. The device features a positive output configuration and utilizes a 20-VFQFN package with an exposed pad. It is classified under PMIC DC DC Switching Controllers and is currently in an active production status.
Feature Summary
- Integrated single-phase synchronous buck topology for efficient power conversion
- Designed specifically for high-performance computer application requirements
- Supports wide input voltage range for flexible system integration
Applications
- Computer motherboard power delivery systems
- CPU core voltage regulation
- High-density point-of-load conversion
Procurement Notes
Verify the specific suffix DMNTXG against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 20-QFN(4x4) outline. Confirm RoHS3 compliance status if required by assembly standards. Check for any recent Product Change Notifications that may affect material composition or manufacturing location.
Selection Notes
Select this component when a single-phase solution is sufficient for the target current load. Compare against multi-phase controllers if higher current capability or reduced input ripple is required. Consider the 600kHz maximum frequency for balancing component size and efficiency. Verify thermal performance within the specified operating temperature range for the intended enclosure.
Part Context
This part belongs to the NCP81270 series, which includes variants like NCP81270CMNTXG. These devices are positioned as dedicated regulators for computing platforms, distinct from general-purpose buck controllers. The series emphasizes simplicity and reliability for single-rail power architectures in modern electronic systems.
Replacement Considerations
NCP81270CMNTXG is listed as a variant within the same family. Verify pinout and electrical parameter equivalence before substitution. No other direct cross-manufacturer replacements are confirmed in public documentation.
