Categories: DC DC Switching Controllers
Quality Control: Learn More
The onsemi NCP81611MNTXG is a 4-phase, non-synchronous, buck controller designed for efficient step-down voltage conversion. This DC-DC controller IC features I2C and PSI serial interfaces for flexible configuration and monitoring. It supports a wide input voltage range of 2.8V to 20V and offers a switching frequency adjustable from 250kHz to 1.2MHz. Control features include current limit, enable, frequency control, power good indication, ramp-up, and soft-start functionality. The device is housed in a 40-QFN (5x5) package, suitable for surface mounting. Its multiple phase architecture makes it ideal for high-power applications in computing, server, and networking equipment.
