Controller IC Chip - Rt8859MGQW RT8859M QFN 56 Chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0969) The RT8859M is a VR12/IMVP7 compliant CPU power controller which includes two voltage rails : a 4/3/2/1 phase synchronous buck controller, the CORE VR, and a single phase buck controller, the AXG VR. The RT8859M adopts G-NAVPTM (Green Native AVP), which is Richtek s proprietary topology derived from finite DC gain compensator with current mode control, making it an easy setting PWM controller, meeting all Intel CPU requirements of AVP (Active Voltage Positioning). Based on the G-NAVPTM topology, the RT8859M also features a quick response mechanism for optimized AVP performance during load transient. The RT8859M supports mode transition function with various operating states. A serial VID (SVID) interface is built in the RT8859M to communicate with Intel VR12/IMVP7 compliant CPU. The RT8859M supports VID on-the-fly function with three different slew rates: Fast, Slow an
