Overview
The NX2601CMTR is a dual synchronous PWM controller IC manufactured by Microsemi Corporation. It integrates an NMOS LDO controller and a 5V bias regulator within a single package. The device utilizes a 32-MLPQ (5x5) surface-mount footprint. It functions as a positive output buck regulator designed for switched-mode power applications. The component supports three-phase operation configurations. It provides control signals for external power stages without internal high-current drivers.
Feature Summary
- Integrates dual synchronous PWM control with dedicated NMOS LDO regulation
- Includes an internal 5V bias regulator to simplify power supply design
- Supports three-phase topology for high-efficiency DC-DC conversion
Applications
- Server and workstation power distribution networks
- Graphics processing unit voltage regulation modules
- High-performance digital logic core power supplies
Procurement Notes
Verify the current production status of the NX2601CMTR before procurement, as it may be classified as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that the specific MLPQ package variant matches the target PCB layout requirements. Request updated lifecycle documentation from the supplier to confirm long-term support or recommended obsolescence alternatives.
Selection Notes
Select this component for designs requiring integrated dual-channel synchronous control and local LDO regulation. Evaluate the thermal performance of the 32-MLPQ package against the system's heat dissipation capabilities. Verify compatibility with the required switching frequency range and input voltage specifications. Consider the integration of the 5V bias regulator to reduce external component count in the control circuitry.
Part Context
The NX2601CMTR belongs to the NX2601 series of power management controllers from Microsemi Corporation. This series targets high-density power conversion applications requiring precise voltage regulation. The component represents a specialized solution for multi-phase buck converters in computing infrastructure. It shares functional similarities with other dual-channel PWM controllers but distinguishes itself through integrated bias and LDO features.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Users should consult Microsemi Corporation directly for official obsolescence notices and recommended replacement components.
