NCP81233MNTXG Description

Short technical summary and product information.

The ON Semiconductor NCP81233MNTXG is a versatile multi-phase synchronous buck controller designed for power management solutions. It features an I2C interface for flexible programming and supports selectable 1-, 2-, 3-, 4-, or 6-phase operation, with the capability to support up to 12 phases using phase doublers.

 

Key electrical specifications include an input voltage range of 4.5 V to 20 V and a switching frequency adjustable from 200 kHz to 1.2 MHz. The controller offers programmable output voltage control, differential voltage and current sensing, and comprehensive protection features such as over-current, over/under-voltage, and thermal shutdown.

 

Packaged in a 52-VFQFN exposed pad, the NCP81233MNTXG is designed for surface mounting. It is suitable for applications requiring precise power management, including telecom, server and storage systems, and graphics card applications. The device also includes integrated 5.35 V and 3.3 V LDOs and is Pb-Free.
