This datasheet details the NCP81266FH, a dual rail, six + two phase buck controller optimized for Intel IMVP8 CPUs in notebook and ultrabook applications.
The NCP81266FH is a dual rail, six + two phase buck solution optimized for Intel IMVP8 CPUs. The multi-phase rail control system is 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.
Key features include an ultra-low offset current monitor amplifier with programmable offset compensation for high accuracy current monitoring, digital soft start ramp, and programmable output voltage slew rates. The device supports dynamic VID feed-forward and meets Intel's IMVP8 specifications, making it suitable for notebook and desktop computer applications.
