® RT8855 4/3/2/1-Phase PWM Controller for AMD AM2/AM2+ CPUs General Description The RT8855 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 RT8855 uses differential inductor DCR current sense to achieve phase current balance and active voltage positioning. Other features include adjustable operating frequency, power good indication, external error-amp compensation, over voltage protection, over current protection and enable/ shutdown for various applications. The RT8855 comes to a small footprint with WQFN-48L 7x7 package.
