Master-slave type leading load compensation voltage stabilizer

Abstract

The invention provides a master-slave type leading load compensation voltage stabilizer which is applied to a circuit of an internal memory buffer; the master-slave type leading load compensation voltage stabilizer comprises a voltage stabilization unit, a master-slave type output stage, a master control unit and an output stage control unit, wherein the voltage stabilization unit is provided with an input end used for receiving reference voltage and feedback voltage, and an output end used for generating regulation voltage; the master-slave type output stage comprises a master output stage and a plurality of slave output stages; the master control unit is used for monitoring the working condition of a circuit load in the internal memory buffer and providing the working information of the circuit load in advance under the condition that the working condition of the circuit load is changed; and the output stage control unit is connected with the master control unit and is used for generating enable signals which respectively correspond to the plurality of slave output stages so as to open and close the plurality of slave output stages according to the working information of the circuit load that is provided in advance, so that the output supply voltage is maintained to be stable. Compared with the prior art, the opening number of the output stages can be controlled in a self-adaptive way according to the working condition of the circuit load, so that the output supply voltage is maintained to be stable, and the performances and the work stability of the circuit load are improved.

Description

technical field [0001] The invention relates to a voltage stabilization technology, in particular to a master-slave leading load compensation voltage stabilization device applied to a memory buffer circuit. Background technique [0002] With the development of electronic technology, an electronic system includes various functional circuits (such as rectification, filtering, voltage transformation, voltage stabilization, signal conversion or signal amplification, etc.) Normal operation needs to be realized through power management, and the main purpose of power management is to control and maintain the normal supply of appropriate current and voltage in the electronic system at any time under different operating states of the electronic system. [0003] The power management circuit can be divided into power regulator (regulator), battery charging / measurement, hot swap, voltage monitoring and other types. Among them, the power regulator is mainly used when the voltage of the p...
