Overview
The NCP81561MNTXG is a single-phase synchronous buck voltage regulator controller manufactured by onsemi. It operates within an input voltage range of 4.75 V to 5.25 V and supports switching frequencies up to 600 kHz. The device integrates current and voltage mode control capabilities for high-performance power delivery. It is housed in a 20-QFN (4x4) package with exposed pad, designed for surface-mount installation. This component belongs to the NCP81561 series under PMIC - Power Management ICs.
Feature Summary
- Integrates dual-mode control supporting both current mode and voltage mode operation for flexible design configurations.
- Features a compact 20-VFQFN package with exposed thermal pad for efficient heat dissipation and space-constrained applications.
- Designed for high-efficiency single-phase synchronous buck conversion with integrated driver outputs.
Applications
- Computer processor core voltage regulation
- High-density point-of-load (POL) converters
- Server and data center power distribution networks
Procurement Notes
Verify the specific suffix 'MNTXG' against the manufacturer datasheet to confirm packaging type and tape-and-reel specifications. Ensure compatibility with IMVP-8 or similar CPU load-line protocols if used in processor power stages. Confirm RoHS3 compliance status through official environmental declarations prior to integration into regulated assemblies.
Selection Notes
Select this controller for applications requiring a single-phase solution with mixed-mode control flexibility. Evaluate thermal performance requirements based on the 20-QFN package characteristics. Compare switching frequency limits against electromagnetic interference constraints. Ensure input voltage stability within the 4.75 V to 5.25 V window for optimal regulation performance.
Part Context
The NCP81561 is part of onsemi's portfolio of high-performance synchronous buck controllers aimed at computing and server markets. It complements other devices in the NCP81xxx series, which offer varying phase counts and control modes. The MNTXG designation indicates the specific reel packaging configuration for automated assembly processes.
