General Description
The RT8862 is an advanced 4/3/2/1-phase synchronous buck controller with 2 integrated MOSFET drivers for Intel VR11/VR10 and AMD K8/K8_M2 CPUs power application. RT8862 adopts state-of-the-art dynamic phase control capability. That achieves high efficiency over wide load range. It uses differential inductor DCR current sense to achieve phase current balance and active voltage
positioning. Other features include adjustable operating frequency, adjustable soft start, power good indication, external error-amp compensation, over voltage protection, over current protection and enable/shutdown for various application. RT8862 comes to a small footprint with
WQFN-48L 7x7 package.
