Overview
The NCP81232MNTXG is a dual-channel/multi-phase switching controller designed for DrMOS applications. It operates with an input voltage range of 4.5 V to 20 V and supports adjustable output voltages from 0.6 V to 5.3 V. The device utilizes pulse width modulation (PWM) control technology and features a 40-pin package with dimensions of 5 mm in length.
Feature Summary
- Dual-channel architecture supporting multi-phase configurations
- Integrated compatibility with DrMOS topologies
- Adjustable output voltage range capability
Applications
- DrMOS power stage control
- Multi-phase voltage regulation systems
- High-performance computing power delivery
Procurement Notes
Verify the specific suffix '115' against official ON Semiconductor documentation, as standard listings typically reference 'NCP81232MNTXG'. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the component matches the required 40-pin QFN package specifications for your design integration.
Selection Notes
Select this controller when designing dual-channel or multi-phase power stages requiring DrMOS integration. It is suitable for applications needing PWM control with adjustable output ranges between 0.6 V and 5.3 V. Consider the 4.5 V to 20 V input voltage window and the 40-pin package constraints during PCB layout and thermal management planning.
Part Context
This component belongs to the NCP8123x series of switching controllers from ON Semiconductor. It shares functional similarities with models like the NCP81234 but is specifically optimized for dual-channel and multi-phase DrMOS applications. The series focuses on high-efficiency power conversion for demanding computing loads.
Replacement Considerations
The NCP81234MNTXG is a related dual-channel/two-phase controller for DrMOS. Verify pinout and feature compatibility before substitution. Other multi-phase controllers may require significant circuit redesign.
