The power module has adjustable output voltage, can be inserted into the slot of the mainboard through the contact pin, and has the advantages of multiple purposes, simple structure and convenient insertion with the mainboard.
Description
Technical field
The present invention relates to voltage transitions field, specifically a kind of contact pin type power module.
Background technology
Along with the progress increasingly of electronic utility, electronic product has goed deep into each market, and provides the voltage conversion operation of power source to become extremely important equally for electronic product.Voltage conversion operation is in the past all in the research and development of products stage, designs power conversion circuit by Power Engineer, then, is connected up by layout engineer, then through Power Engineer inspection, finally on mainboard, completes voltage conversion operation.Often different special projects, identical circuit, engineers all will carry out the copy operation of repetition, and this adds workload undoubtedly.Meanwhile, the accuracy of work is also reduced.
At present, the workload, the simply and easily voltage transformation module designed on mainboard that how effectively to reduce Power Engineer and layout engineer are the problems needing to solve.
summary of the invention
Technical assignment of the present invention is for above deficiency, a kind of contact pin type power module is provided, solving voltage transitions design cannot the problem of a module multiple purpose, realizes integrated, the single module multiple purpose of power module, does again design without the need to Power Engineer and layout engineer.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of contact pin type power module, comprise pcb board, pcb board is provided with DC-DC voltage conversion chip, input capacitance, output capacitance, inductance, resistance, the backing weld of pcb board has contact pin.
Further, pcb board is provided with feedback circuit, feedback line comprises pull down resistor R1, pull-up resistor R2, and feedback line connects DC-DC voltage conversion chip.
Further, the output voltage of power module is adjustable, and output voltage computing formula is: VO=Vfb × (R1+R2)/R1, R1 is feedback line pull down resistor, and R2 is feedback line pull-up resistor, and Vfb is the feedback pin of voltage conversion chip.
Further, a kind of contact pin type power module is in sum plugged on the slot of mainboard by contact pin.
Compared to the prior art a kind of contact pin type power module of the present invention, has following beneficial effect:
1, power module voltage of the present invention is adjustable, can meet multiple design requirement, and lowest high-current value needed on mainboard is less than voltage conversion chip output-current rating value on power module and all can uses this power module;
2, power module of the present invention can realize and simple and easy plug between required power supply mainboard, even if mainboard is scrapped, this power module is still recyclable;
3, power module of the present invention is connected by contact pin with required power supply mainboard, belongs to independent existence, and on minimizing power module, inductance is to the interference of required power supply mainboard signal.
