Overview
The NCP81526CSMNTXG is a DC-DC switching controller manufactured by onsemi. It is designed for high-performance computing applications, specifically supporting Intel Core processors. The device features a multi-phase architecture with four output phases to deliver stable power rails. It operates within an input voltage range of 4.5V to 20V and supports a switching frequency between 250kHz and 1.2MHz. The component is housed in a 40-pin QFN package measuring 5x5 mm and is rated for operation temperatures from -10°C to 100°C.
Feature Summary
- Supports four-phase synchronous buck conversion for CPU core power delivery
- Integrates I2C and PSI serial interfaces for digital control and monitoring
- Includes built-in protection mechanisms such as over-current limiting and soft-start functionality
Applications
- Intel Core processor power supply designs
- High-performance computing server platforms
- Desktop motherboard VRM circuits
Procurement Notes
Verify the specific suffix 'CS' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the selected packaging option matches the required manufacturing process, whether reel or cut tape. Confirm RoHS compliance status directly with the supplier documentation prior to finalizing procurement orders.
Selection Notes
Select this controller when designing power stages for Intel Core architectures requiring four independent output phases. Evaluate the thermal performance requirements of the 40-QFN package relative to the expected load current. Verify that the system design supports the necessary I2C or PSI communication protocols for configuration and telemetry.
Part Context
This component belongs to onsemi's portfolio of professional power management integrated circuits tailored for demanding computing environments. It serves as a critical interface between the main power supply and the central processing unit, ensuring precise voltage regulation and dynamic response during varying computational loads.
Replacement Considerations
Consult official substitution lists for compatible controllers within the same series. Verify that any alternative part maintains identical phase count, package dimensions, and communication protocol support.
