8 + 1 Phase Output Controller with SVID Interface for Computer CPU Applications NCP81566 The NCP81566 is a dual rail, eight plus one 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 NCP81566 has an ultra low offset current monitor amp.
