Embodiment Construction

[0021] The invention provides a realization method of an adjustable DC power supply, adding a TPS54360 chip and a voltage feedback circuit at the input end of the power supply,

[0022] By comparing the FB pin voltage of the TPS54360 chip with the output reference voltage of the voltage feedback circuit, if the FB pin voltage is greater than the reference voltage, the power supply output will decrease, and when the FB pin voltage is lower than the reference voltage, the power supply output will increase, realizing an adjustable DC power supply .

[0023] At the same time, an output device of an adjustable DC power supply and an output circuit of an adjustable DC power supply corresponding to the above method are provided.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are no...

Abstract

The invention discloses an implementation method of an adjustable direct-current power supply, and relates to the technical field of adjustable power supplies. A TPS54360 chip and a voltage feedback circuit are additionally arranged on the input end of the power supply. The FB pin voltage of the TPS54360 chip is compared with the output reference voltage of the voltage feedback circuit. If the FBpin voltage is greater than the reference voltage, the power supply output is reduced. if the FB pin voltage is less than the reference voltage, the power supply output is increased. The adjustable direct-current power supply is realized. By utilizing the method provided by the invention, the power supply output can be adjusted by changing the output reference voltage of the voltage feedback circuit. The adjustable direct-current power supply can be adjusted from 0V through the TPS54360 chip. The adjusting process is very smooth and easy to operate. The method is convenient to implement and the like, can be applied to various electronic devices or products needing the adjustable direct-current power supply, and is wide in application prospect.
