Module interface

VIN+: DC input orthopedic 6V-25V (needs to be above 1V above 1V)

GND: DC input negative electrode, connecting negative poles with the same output.

+(Out+): DC output positive poles.

-(GND): DC output negative poles, connecting negative input negative electrodes.

Must -see:

1. The product input should be greater than the output voltage. It can maintain the best pressure difference between 1V. The input cannot be connected.

2. It is best to disconnect the power when the wiring, otherwise when the voltage is high, it is easy to spark, so that there will be a certain risk to hit the chip and penetrate the chip.

3. The wiring cannot be too detailed, ensuring that the wire can withstand the corresponding current

4. Sensory loads are well protected to avoid excessive reverse electromotives beyond the scope of chip tolerance.

5. The larger the module uses, the closer the current is to the maximum current.The greater the fever, pay attention to heat dissipation when using.

6. When adding heat dissipation without external, it is recommended to use the current below 5A, and more than 5A requires additional heat dissipation, otherwise it will overheat the output.

7. It is recommended to use the voltage below 24V. If the power supply voltage should not be very stable, the peak voltage exceeds 25V will trigger the internal voltage protection of the chip. To operate stable, there will be some margin.
