3A Mini DC-DC Buck Step Down Converter Board Module 6V-40V to 5V 9V 12V 24V DC DC Voltage Regulator PCB Board Power Buck Module

Product features:

Stable performance with multiple working modes available

2 input voltages, DC 6-32V/DC 6-40V/, 4 step-down DC5V/9V/12V/24V

Low ripple design, no false current mark

This module can achieve considerable parameters and functions in a very small volume.

The module size is very small, and the heat dissipation area is limited. It is a normal phenomenon for high-power output to generate heat. We use high-quality materials, so there is no need to worry about heat affecting the lifespan.

Product Description:

The original chip is used, with a maximum output of 3A, but can continuously output current far superior to other chips in the same industry. Without heat dissipation, 24V can continuously output 2A current (48W). If the board is attached to the bottom plate to increase heat dissipation, it can continuously output 3A. Similarly, similar to a module, the pressure difference required for voltage reduction is also relatively low. The efficiency should also be higher.

Module terminal definition:

IN+: Module power supply 6-32V input positive pole (input must be greater than output voltage)

IN -: Module input negative (output negative)

OUT+: module output positive pole

OUT -: Module output negative (input negative)

Precautions for use:

◆ The input of the product should be greater than the output voltage, and it is best to maintain a voltage difference of more than 1V. The input should not be connected in reverse, and the circuit should be connected in reverse.

It is best to disconnect the power supply when wiring, otherwise when the voltage is high, it is easy to spark, which will have a certain risk of hitting the chip and breaking it down.

The wiring should not be too thin to ensure that the wire can withstand the corresponding current.

◆ Protect the inductive load to avoid excessive reverse electromotive force exceeding the range of the chip.

The higher the power used by the module, the closer the current is to the maximum current. The heat will increase, so pay attention to heat dissipation when using.

When encountering problems during use, contact customer service must cooperate with them to provide wiring pictures, videos, etc. It is not acceptable to only provide text information.
