Title: Dual-switching and dual-linear power controller chip

Abstract: A hybrid 4-in-1 power controller chip for a PC mainboard which integrates a synchronous buck switching regulator to supply the CPU core voltage, a standard buck switching regulator for I/O circuits, a linear controller for the GTL bus, and a linear regulator with built-in pass transistor for a clock generator. Therefore, a hybrid power system for a PC mainboard is constructed.
