NCP81246MNTXG Information

NCP81246 Three-Rail Controller

ON Semiconductor NCP81246 Three-Rail Controller offers an optimized 3-rail multi-phase buck solution for Intel IMVP8 compatible CPUs. The NCP81246 includes a 2-phase controller and two 1-phase controllers. The 2-phase controller provides differential inductor DCR current sensing, true differential voltage sensing, input voltage feed-forward, and adaptive voltage positioning to accurately regulate power for the IMVP8 Rail2. Designers can use the two 1-phase controllers for the Rail1, Rail3 and, Rail4 rails. The two single-phase controllers support Core, GT, and SA rails in the 2-1-1, 1-2-1, and 1-1-1 configurations. The single-phase rails include a programmable ultra-low offset current monitor amplifier to deliver ultra-high accuracy current monitoring. The 2-phase and 1-phase controllers use ON Semiconductor’s patented high performance RPM operation. The RPM operation maximizes transient response while ensuring for smooth transitions between discontinuous frequency scaling operation and continuous mode full-power operation. The NCP81246 Three-Rail Controller is well-suited for Notebook and Ultrabook applications.Learn More
