The RT8868A is a 4/3/2/1-phase synchronous buck controller with two integrated MOSFET drivers for CPU power application and a single-phase buck with integrated MOSFET driver for North-Bridge (NB) chipset. The RT8868A uses differential inductor DCR current sense to achieve phase current balance and active voltage positioning. Other features include adjustable.
include adjustable operating frequency, power good indication, external error-amp compensation, over voltage protection, over current protection and enable/shutdown for various applications. The RT8868A comes in a small footprint with WQFN-48L 7x7 package.
