Overview
The NCP81118MNTWG is a switching voltage regulator controller manufactured by onsemi. It is packaged in a 36-pin QFN (Quad Flat No-leads) configuration. The component functions as a VR controller designed for power management applications. Official documentation identifies it within the Switching Voltage Regulators category.
Feature Summary
- Integrated control logic for synchronous buck converter topologies
- Designed for high-efficiency voltage regulation in compact form factors
Applications
- Server and data center power distribution
- Graphics processing unit (GPU) core voltage regulation
- High-performance computing board power stages
Procurement Notes
Verify current manufacturing status before procurement, as sources indicate this product may be discontinued or no longer manufactured by onsemi. If unavailable directly from the manufacturer, check authorized distributors like Rochester Electronics for existing stock. Ensure the 36QFN package matches your PCB footprint requirements. Confirm that the specific suffix MNTWG aligns with your required tape and reel specifications.
Selection Notes
Select this component when a dedicated controller for synchronous buck conversion is required rather than an integrated power stage. The 36-pin QFN package supports high-current applications requiring multiple external MOSFETs. Consider thermal dissipation capabilities of the PCB layout, as the controller manages high-power stages. Verify compatibility with the target load transient requirements and input voltage range specified in the official datasheet.
Part Context
This part belongs to onsemi's portfolio of analog and mixed-signal power management solutions. It is categorized under switching voltage regulators. The device complements other buck controllers in the series, offering a specialized solution for complex multi-phase power delivery systems where external gate drivers and MOSFETs are utilized for flexibility and performance optimization.
Replacement Considerations
Check for direct pin-to-pin replacements within the NCP81xxx series if available. Since the part is noted as potentially discontinued, evaluate equivalent controllers from other manufacturers such as Texas Instruments or Analog Devices that offer similar 36-pin QFN packages and synchronous buck control features.
