RT8881A
Dual-Channel, Multi-Phase PWM Controller with I2C Interface for AMD SVI2 CPU Power Supply
General Description
The RT8881A is a multi-phases PWM controller.
Moreover, it is compliant with AMD SVI2 Voltage
Regulator Specification to support both CPU core (VDD) and Northbridge portion (VDDNB) of the CPU.
The RT8881A adopts the G-NAVPTM (Green-Native AVP), which is a Richtek's proprietary topology.
The G-NAVP makes it an easy setting controller to meet all AMD AVP (Adaptive Voltage Positioning) requirements.
The droop is easily programmed by setting the DC gain of the error amplifier.
With proper compensation, the load transient response can achieve optimized AVP performance.
