Abstract

The invention discloses a voltage-reduction regulation circuit. The voltage-reduction regulation circuit comprises a switch tube, a feedback module and a regulation module. The first end of the switchtube is used as an input voltage end, the second end of the switch tube is used as an output voltage end, the first end of the feedback module is connected with the second end of the switch tube, thesecond end of the feedback module is connected with the first end of the regulation module, and the second end of the regulation module is connected with the driving end of the switch tube. Accordingto the voltage-reduction regulation circuit, the output voltage is processed by the feedback module to obtain the feedback voltage so as to realize effective control when the output voltage is too high or too low, and the voltage at the driving end of the switch tube is adjusted by the feedback voltage and the quasi-level voltage so as to adjust the impedance of the switch tube so as to realize voltage-reduction adjustment of any pressure difference, and the voltage-reduction regulation circuit has the advantages of simple structure, high reliability, good stability and the like.

Description

Technical field [0001] The present invention relates to the field of step-down, in particular to a step-down regulating circuit. Background technique [0002] The existing step-down regulation technology generally uses the input voltage directly as the driving voltage to drive the MOSFET (MetalOxide Semiconductor Field Effect Transistor, metal-oxide semiconductor field effect transistor) to turn on to achieve the step-down output. Due to the conduction of the MOSFET The existence of voltage causes a limit on the voltage difference between the input voltage and the output voltage. Therefore, the existing linear step-down regulation technology has relatively large restrictions on application scenarios that require different voltage differences, and is less flexible. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Summary of the invention [0004] The purpose of the present invention is ...
