Abstract

A circuit for generating supply voltage to chipsets of a motherboard includes a voltage division module comprising a plurality of resistors, a control module comprising an amplifier, and an output module comprising a MOS transistor. A plus input terminal of the amplifier is connected to a node between the resistors An output terminal of the amplifier is connected to a grid of the MOS transistor. A drain of the MOS transistor is connected to a core voltage. A source of the MOS transistor is connected to an output terminal of the circuit.
