General Description
The RT8841 is a 4/3/2/1-phase synchronous buck controller with 2 integrated MOSFET drivers for VR11 CPU power application. RT8841 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 applications. RT8841 comes to a small footprint with WQFN-40L 6x6 package
