Product Summary

The RT8802AGQV is a 2/3/4/5-phase synchronous buck controller specifically designed to power Intel/AMD next generation microprocessors. It implements an internal 8-bit DAC that is identified by VID code of microprocessor directly. The RT8802AGQV generates VID table that conform to Intel VRD10.x and VRD11 core power with 6.25mV increments and 0.5% accuracy. The applications of the RT8802AGQV include Intel/AMD New generation microprocessor for Desktop PC and Motherboard, Low Output Voltage, High power density DC-DC Converters, Voltage Regulator Modules.
