RT8871A/B
4/3/2-Phase PWM Controller for AMD AM2/AM2+/AM3/FM1 CPUs
General Description
The RT8871A/B is a 4/3/2-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 RT8871A/B 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 RT8871A/B comes in a small footprint with WQFN48L 7x7 and WQFN-48L 6x6...
