Overview
The NCP81109EMNTXG is a single-phase voltage regulator controller from onsemi, designed for high-performance CPU power delivery. It utilizes a buck topology and features an integrated high-side driver with a maximum continuous output current capability of 14 A. The device supports an output voltage range from 0 V to 2.3 V and operates within a junction temperature range of -10°C to +100°C. It is housed in a compact 48-QFN (6x6 mm) package with an exposed pad for thermal management.
Feature Summary
- Integrated high-side power switch capable of delivering up to 14 A continuous load current
- Supports low output voltages down to 0 V for advanced processor core regulation
- Compact 48-pin QFN package optimized for thermal dissipation and board space efficiency
Applications
- CPU core voltage regulation in desktop and server platforms
- High-current point-of-load conversion for processors requiring fast transient response
- Single-phase VR designs for next-generation microprocessors
Procurement Notes
Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix 'EMNTXG' matches the required tape-and-reel packaging configuration. Check for moisture sensitivity level (MSL) handling requirements prior to assembly. Ensure the source provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when designing single-phase VRMs requiring integrated high-side switching without external gate drivers. Consider the 14 A current limit and 0-2.3 V output range against target processor specifications. Evaluate the 48-QFN footprint for PCB layout constraints and thermal vias. Compare against other NCP81109 variants if different thermal or pinout options are needed.
Part Context
This part belongs to the NCP81109 family of single-phase voltage regulators. Variants such as NCP81109DMNTXG and NCP81109GMNTXG share similar architectural foundations but may differ in thermal performance, package variations, or specific electrical characteristics. The family targets high-efficiency power delivery for demanding computing applications.
Replacement Considerations
Direct substitutes include other NCP81109 variants like NCP81109DMNTXG or NCP81109GMNTXG, provided their specific electrical parameters align with the design requirements. Verify pin compatibility and thermal characteristics before substitution.
