NCP81274MNTXG Description

Short technical summary and product information.

The NCP81274MNTXG is an 8-phase buck PWM controller designed for high-current applications. It provides eight PWM outputs for driving external MOSFETs in a step-down topology.

 

Key electrical specifications include a supply voltage range of 4.5V to 20V and a switching frequency adjustable from 250kHz to 1.2MHz (8-phase operation). The controller features current limit, enable, frequency control, power good, ramp, and soft start. It supports I²C and PSI serial interfaces for configuration.

 

The device is housed in a 40-VFQFN exposed pad package (40-QFN 5x5mm) for surface mount assembly. Operating temperature range is -10°C to 100°C. It is RoHS3 compliant and REACH unaffected.
