The peak of the capacitance is 6A, which can continue to output 5A in a short time (chip will pass the warmth households). If the actual and open environment is not added, the 3.3V sustainable output is 3.8A, 5V sustainable output of 3.5A, 9V, and 12V sustainable output3A, if you need a larger current, you need to strengthen the heat dissipation appropriately.It is recommended to leave a certain amount of balance in normal selection.

The thickness of the board is 4.5mm (3.3V and 5V inductors 3r3) and 6.4mm (9V and 12V inductors 4R7) (different batches of inductors will have a certain error). Different output voltage inductance values ​​are different. Our pictures do not have every voltage to take pictures.Receive the real object

Module interface

IN+: DC input orthopedic 4.5V-18V (needs to be higher than output 1V).

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

OUT+: DC output positive poles.

OUT-: DC output negative electrode, connects to the negative electrode input.

The product input should be greater than the output voltage. It can maintain the best pressure difference between 1V.

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 electrometer 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 17V. If the supply voltage is not very stable, the peak voltage exceeds 18V will trigger the internal voltage protection of the chip. In order to run stable, there will be some margin.
