Overview
NCP81245 Three-Rail Output Controller with Single Intel Proprietary Interface for Desktop and Notebook CPU Applications www.
onsemi.
com The NCP81245 (3+3+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 NCP81245 has an ultra−low offset current monitor amplifier with programmable offset compensation for high−accuracy current monitoring.
Three−Phase Rails Feature • Dual Edge Modulation for Fastest Initial Response to Transient Loading • High Performance Operational Error Amplifier • Di...
