GENERAL DESCRIPTION

RT8802A generates VID table that conform to Intel® VRD10.x and VRD11 core power with 6.25mV increments and 0.5% accuracy. RT8802A adopts innovative time-sharing DCR current sensing technique to sense phase currents for phase current balance, load line setting and over current protection. Using a common GM to sense all phase currents eliminates offset and linearity variation between GMs in conventional current sensing methods. As sub-milli-ohm-grade inductors are widely used in modern motherboards, slight offset and linearity mismatch will cause considerable current shift between phases. This technique ensures good current balance in mass production. Other features include over current protection, programmable soft start, over voltage protection, and output offset setting. RT8802A comes to a small footprint package with VQFN-40L 6x6.
