Abstract

The invention discloses a charge pump regulator, a memory and Internet of things equipment. The charge pump regulator comprises a charge pump circuit, a voltage dividing circuit, a clock oscillator, a first voltage comparison circuit and a logic control unit, wherein the output end of the charge pump circuit is connected with the output end of the charge pump regulator and outputs stable voltage; the voltage dividing circuit is used for carrying out voltage dividing on the stable voltage to output divided voltage; the clock oscillator is used for providing driving clock signals for the charge pump circuit; reference voltage and divided voltage are inputted to the first input end and the second input end of the first voltage comparison circuit respectively, and a first comparison result and a second comparison result are outputted; and the logic control unit is used for outputting first control level to the clock oscillator according to the first comparison result and the second comparison result, and when the first comparison result and / or the second comparison result indicate(s) that the stable voltage is smaller than a lower limit value or larger than an upper limit value, the first control level outputted by the logic control unit controls the clock oscillator to output driving clock signals or stop outputting the driving clock signals. The standby power consumption of the charge pump regulator can be reduced.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a charge pump regulator, a memory, and an Internet of Things device. Background technique [0002] With the development of electronic information technology, low power consumption design and application of memory products play an important role in electronic systems. A charge pump is a switched capacitor voltage converter with high conversion efficiency and simple peripheral circuits. It is widely used in modern power management circuits and is very suitable for memory, IoT devices and portable applications. [0003] A charge pump, also known as a switched capacitor voltage converter, can include a reference circuit, a comparison circuit, a conversion circuit, and a control circuit. The voltage boost is realized through switch arrays, oscillators, logic circuits, and comparison circuits, and capacitors are used to store energy. The charge pump can use a pulse frequency m...
