RT8170A - Single-Phase Controller

Description

The RT8170A is a single phase CPU power controller with one integrated driver for VR12.5 and VR12.6 compliant.

Features

  • a quick response mechanism for optimized AVP performance during load transient. The RT8170A supports mode transition function with various operating states. A Serial VID (SVID) interface is built in the RT8170A to communicate with Intel VR12.5 and VR12.6 compliant CPU. The RT8170A supports VID on-the-fly function with different slew rates. By utilizing the G-NAVPTM topology, the operating frequency of the RT8170A varies with VID, load current and input voltage to further enhance the efficiency e.

® RT8170A Single-Phase Controller with Integrated Driver for VR12.5 and VR12.6 Mobile CPU Core Power Supply General Description The RT8170A is a single phase CPU power controller with one integrated driver for VR12.5 and VR12.6 compliant. The RT8170A adopts the G-NAVPTM (Green Native AVP) which is Richtek's proprietary topology derived from finite DC gain of EA amplifier with current mode control, making it easy to set the droop to meet all Intel CPU requirements of AVP (Adaptive Voltage Positioning). Based on the GNAVPTM topology, the RT8170A also features a quick response mechanism for optimized AVP performance during load transient. The RT8170A supports mode transition function with various operating states.
