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 amplifier with programmable offset compensation for high accuracy current monitoring. Features • Vin Range 4.5 V to 21 V • Startup into Pre−Charged Loads While Avoiding False OVP • Digital Soft Start Ramp • Adjustable Vboot • High Impedance Differential Output Voltage Amplifier • Dual VID Table Support to Be Compatible with IMVP9.
