NCP81243MNTXG Description

Short technical summary and product information.

The NCP81243MNTXG from ON Semiconductor is a dual output controller optimized for Intel IMVP8 CPUs. This device offers five PWM drive signals configurable for various setups, providing accurately regulated power for desktop and notebook applications.

 

Key features include true differential voltage and inductor DCR current sensing, input voltage feed-forward, and adaptive voltage positioning. The control system utilizes Dual-Edge pulse-width modulation (PWM) combined with DCR current sensing for rapid response to dynamic load events. It supports phase shedding during light load operation and auto frequency scaling while maintaining transient performance.

 

This controller is housed in a 52-VFQFN exposed pad package and supports surface mount installation. It operates within a voltage range of 4.5V to 20V and an ambient temperature range of -40°C to 125°C. The switching frequency can be set between 300 kHz and 1.4 MHz.

 

Applications include desktop and notebook processors, and gaming systems requiring precise power management.
