8 + 2 Phase Output Controller with SVID Interface for Notebook and Ultrabook CPU Applications NCP81228 The NCP81228 is a dual rail, eight + 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. This provides an ultra−fast initial response to dynamic load events and reduced system cost. The NCP81228 has an ultra−low offset current monitor amplifier with programmable offset compensation for high accuracy current monitoring. Features  Vin Range 4.
