Produktinformationen "NCP81215PMNTXG"


Three Output Controller with Single SVID Interface for Desktop and Notebook CPU Applications

The NCP81215P (4 + 2 + 1 phase) three−output buck solution is optimized for Intel’s IMVP8 CPUs.
The two multi−phase rail control systems are based on Dual−Edge pulse−width modulation (PWM) combined with DCR current sensing providing an ultra fast initial response to dynamic load events and reduced system cost.
The single−phase rail makes use of ON Semiconductor’s patented high performance RPM operation. RPM control maximizes transient response while allowing for smooth transitions between discontinuous−frequency−scaling operation and continuous−mode full−power operation. The NCP81215P has an ultra−low offset current monitor amplifier with programmable offset compensation for high−accuracy current monitoring.
