NCP81228
NCP81228 is 8 + 2 Phase Output Controller manufactured by onsemi.
8 + 2 Phase Output Controller with SVID Interface for Notebook and Ultrabook CPU Applications
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) bined 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 pensation for high accuracy current monitoring.
