Description
Technical field
This utility model relates to power module technical field, is specifically related to a kind of two-way or the power module of multiple-channel output positive voltage。
Background technology
Multiplex output circuit refers to by multiple winding internal coilings, the circuit form organizing voltage of output simultaneously on a transformator more。Each group scope range of the fluctuation of voltage of output voltage in multiplex output circuit, load capacity is associated with each other, influence each other。
At present, in power module market, the power module of circulation is divided into single channel output and two kinds of standards of doubleway output, and the power module of doubleway output to be two-way voltage equal and for series relationship, namely export a road positive voltage and a road negative voltage, output pin is the negative arrangement of normal incidence。But miniaturization and the multifunction along with electronic product, it is necessary to the occasion of two-way or the above positive voltage of multichannel gets more and more, and the situation of multiple amplitude also occurs in output voltage。If using existing traditional power module to power, it is necessary to multiple power modules are powered and realized demand, so both add the difficulty of designer's type selecting, too increase volume and the cost of product。Based on this kind of situation, in conjunction with the Circuit theory of conventional power source module, it is necessary to produce the multiple power module that can provide two-way or multichannel positive voltage。
Utility model content
The purpose of this utility model is in that the power module providing a kind of two-way or multiple-channel output positive voltage, its exportable multichannel positive voltage, and output voltage precision is high。
For achieving the above object, this utility model provides following technical scheme:
A kind of voltage sensor with micro-system processing module, including primary coil and several secondary coil, also including the first binding post and the second binding post, the head end of described each secondary coil all receives the first binding post, and the tail end of described each secondary coil all receives the second binding post。
Further, also include secondary output voltage and adjust circuit, described secondary output voltage adjusts circuit and is connected with several secondary coils respectively, described secondary output voltage adjusts circuit and is also associated with voltage feedback circuit, described voltage feedback circuit is also connected with being provided with power supply control type chip, and described power supply control type chip is connected with primary coil。
Compared with prior art, the beneficial effects of the utility model are: this utility model is by being connected the head end of several secondary coils with head end, tail end is connected with tail end, output multi-channel positive voltage can be realized, so can reach the satisfied little power-supply system of a power module to power, reduce the volume of power supply, improve power supply reliability, and can significantly save production cost, secondary coil is connected to the precision height that secondary output voltage adjusts circuit and voltage feedback circuit can make voltage export simultaneously。
