LM2596 DC-DC Adjustable Step-down Module

Product information:
Module highlights:
1. Comfortable price, intelligent and humanized design, with high cost performance!
2. On-board voltmeter, voltmeter can be self-calibrated, there will never be the problem of inaccurate voltmeter!
Module performance and features:
With voltmeter display and voltmeter self-calibration. More advanced voltage microprocessor is adopted, voltmeter error ± 0.05V, range 0~40V. (To ensure the accuracy of voltmeter, please ensure that the input voltage is above 4.5V)
Touch button to switch the measurement input or output voltage, and there is an indicator light showing which voltage is being measured, and save the setting, even if the power is off and then turn on.
The voltmeter can be closed and can be easily achieved by touching button on the left when it is not needed.
With wiring terminal, it is convenient to use without soldering iron, and bonding wire wiring points are retained.
Input voltage 4.0~40V. (The input voltage must be more than 1.5V higher than the output voltage)
The adjustable output voltage range is continuously adjustable from 1.25V to 37v. (The input voltage must be 1.5V higher than the output voltage)
The output current is 3A. It is recommended to use it within 2.0A. The large current needs to enhance heat dissipation.
Output power 20W, more than 15W please strengthen heat dissipation.
High conversion efficiency, with an average of 88% (efficiency is related to input, output voltage, current and differential pressure)
With reverse connection protection, reverse connection does not burn
With overheating protection and short circuit protection functions
Size 6.1*3.4 * 12cm (length * width * height)
