The input and output maximum 3.5A (the output does not exceed 3.5A at the time of antihypertension, and the input does not exceed 3.5A when the voltage voltage).Built -in 4 low -resistance MOS, so that the module can achieve a higher power lifting output at a very small volume, and the module's ultra -low power consumption also enables it to apply to the application of battery power.

Module interface

Vin+: DC input orthopedic 3V-20V.

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

OUT+: DC output positive poles.

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

EN (back on the board): Module work enable, low level off, default output work.

The input and output maximum 3.5A (the output does not exceed 3.5A at the time of antihypertension, and the input does not exceed 3.5A when the voltage voltage).It should be noted that when the input and output voltage is less than 4V, the current will decrease.

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.

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

The load is well protected to avoid excessive reverse electrical momentum beyond the scope of chip tolerance.

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

When there is no heat dissipation, it is recommended to use the current below 3A, and more than 3A requires additional heat dissipation, otherwise the output will be overheated.

It is recommended to use the voltage below 19V. If the supply voltage should not be very stable, the peak voltage exceeds 20V will trigger the internal voltage protection of the chip. In order to stable operation, there will be some margin.
