RT8856 Multi-Phase PWM Controller f or CPU Core Power Supply General D escription The RT8856 is a single/dual phase PWM controller with two integrated MOSFETdrivers. Moreover , it is compli ant with Intel IMVP6.5Voltage Regulator Spe cification to ful fill its mobile CPU Vcore power supply requirements. The RT8856 adopts NAVPTM (Native AVP) which is Richtek's proprietary topology derived from f inite DC gain compensator peak current mode, ma king it a n easy setting PWM controller that meets all Intel AVP (Active Voltage Positioning) mobile CPU requirements. The output voltage of the RT8856 is set by 7-bit VID code. The built-in high a ccuracy DAC converts the VID code ranging from 0Vto 1.5Vwith 12.5mVper step.The syste m accuracy of the controller ca n rea ch 1.5%.
