LM2596 Step-down 3A DC-DC converter with display and voltmeter

The Universal LM2596S DC-DC converter, with an adjustable output voltage in the range 3.2-35V and a maximum current of up to 3A, features an on-board voltmeter. The voltmeter allows both input and output voltages to be measured, so both voltages can be easily switched and monitored using a switch on the board. The module provides precise output voltage regulation and is short-circuit protected, which increases the safety of use. It is important to note that this module reduces voltage, which means that the output voltage must not exceed the input voltage. Method of use:

* IN+ Positive pole of the input voltage

* IN- Negative pole of the input voltage (ground)

* OUT+ Positive pole of the output voltage

* OUT- Negative pole of the output voltage (ground)

Specification:

* Input voltage: 3.2V to 40V

* Output voltage: 3.2V to 35V, lower than input voltage

* Maximum Output Current: 3A with cooling, up to 2A without heatsink

* Controller: LM2596, documentation available
