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.
