The invention discloses an MOS system voltage stabilizer. The output end of a power switch circuit is electrically connected with the input end of a simultaneous buck-boost transformer, and the two output ends of the simultaneous buck-boost transformer are electrically connected with the input end of a power output module and the input end of a data acquisition module respectively. The output endof the power output module is electrically connected with the input end of a data acquisition module, the output end of the data acquisition module is electrically connected with the input end of a detection and verification circuit, and the output end of the detection and verification circuit is electrically connected with the input end of a main control circuit. Safe and stable voltage output isprovided for high, low and frequent changes of commercial power input voltage, and the voltage stabilizer is characterized in that the voltage stabilizing input range is wide (the voltage stabilizinginput range can be designed to be unequal to increase and decrease voltage and be used in regions with low or high external voltage); the output precision is high, the response adjustment is fast (voltage adjustment or output voltage disconnection is completed by one alternating current wave modulation), and no impact voltage exists at the moment of power failure and power on.
Description
technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to a MOS system voltage stabilizer. Background technique [0002] Voltage regulators are widely used in a variety of handheld and portable devices. With the diversification of equipment types and the complexity of functions, more and more stringent requirements are put forward for the power consumption and stability of power modules. The advantages of low cost and easy integration have been continuously researched. [0003] Conventional voltage regulators will be paralyzed if the on-chip reference voltage generating circuit fails, limiting the yield of the voltage regulator below the reference yield. Contents of the invention [0004] The object of the present invention is to provide a MOS system voltage regulator to solve the problems raised in the background art above. [0005] In order to achieve the above object, the present invention provides the following ...
