Module description



The LM2596 is a step-down power management monolithic integrated circuit switching voltage regulator, capable of outputting 3A of drive current, while having very good linearity and load regulation characteristics. This module integrates 4 LM2596, which can simultaneously output 3.3V, 5V, 12V, ADJ four groups of power supply, the module layout and wiring strictly in accordance with the design specifications of the power circuit; generous materials, using chip aluminum electrolytic capacitors, high Q high-power inductors In order to ensure the stable output voltage, the window processing on the back of the PCB board is more conducive to the heat dissipation of the LM2596 chip. It is suitable for the power requirements of student learning competitions and company or individual project development.


Precautions for using the module



(1) The module belongs to the step-down type module, the input voltage needs to be greater than the output of more than 1V to stabilize the output.

(2) The heating of the module is mainly determined by the input and output voltage difference and the load current. Please choose and use the power module reasonably; generally you need to reserve 30% of the surplus.

(3) The module generates heat during use, please purchasers to enhance heat dissipation according to the actual situation. When carrying a large load, heat sinks, air cooling, etc. can be added appropriately.

(4) When using capacitive or inductive loads, the instantaneous current of the load cannot be too large, otherwise the module may be damaged.


Frequently asked questions


Q: What is the output range of ADJ? What is the output current?

A: The ADJ output range is 1.2V to Vin-1V. The maximum is 3A, and the output current will be less than 3A when the input-output voltage difference is large.

Q: Can the module outputs be connected in parallel or in series?

A: When the output voltages are equal, they can be connected in parallel, but not in series. Each channel is independent, but it will not be isolated and cannot be connected in series.

Q: Is the mounting hole grounded? Can the module output negative voltage?

A: The mounting hole is not grounded, and the module can only reduce the positive voltage and cannot output the negative voltage.
