DATA SHEET www.onsemi.com 6 + 2 Phase Output Controller with SVID Interface for Computer CPU Applications NCP81567 The NCP81567 is a two rail, six plus two phase buck solution optimized for Intel’s IMVP9.2 CPUs.

The multi phase rail control system is based on Dual Edge pulse width modulation (PWM) combined with DCR current sensing.

This provides an ultra fast initial response to dynamic load events and reduced system cost.

The NCP81567 has an ultra
