Input voltage range: DC 3.2V to 40V (The input voltage must be 1.5V higher than the output voltage. It cannot be boosted)

Output voltage range: DC 1.25V to 35V continuously adjustable voltage, high efficiency (maximum 92%), the maximum output current is 3A.

Measured 12V input, 5V output current 1A load regulation rate is less than 1%

Note: This is a step-down module, and the input voltage must be higher than the output voltage.
If the output current is greater than 2.5A (or the output power is greater than 10W), please add a heat sink to work for a long time.

LM2596 DC-DC adjustable step-down module with voltmeter display with digital voltage accuracy calibration

Create the highest cost performance of similar products and create the best-selling LM2596 with digital display module! ! !

Other LM2596 modules have no output short-circuit protection. Once the output is short-circuited, the module will be destroyed immediately, and the current output capacity is less than 1.8A. This module uses original LM2596, large chip, output short circuit protection, high current 3A.

Module highlights:

1. Comfortable price, intelligent and user-friendly design, with super high cost performance!
2. On-board voltmeter, the voltmeter can be self-calibrated, there will never be the problem of inaccurate voltmeter!
Module performance and characteristics:

●With voltmeter display and the voltmeter can be self-calibrated. Using a more advanced voltage microprocessor, the error of the voltmeter is ±0.05V, and the range is 0~40V. (To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)
●Touch the button to switch between measuring input or output voltage, and there is an indicator light to show which voltage is being measured, and the setting is saved, even if the power is turned off and on again.
●The voltmeter can be turned off, and it can be easily realized by touching the left button when it is not needed.
●With terminal blocks, it is easy to use without soldering iron, and the connection points of welding wires are reserved.
●Input voltage 4.0~40V. (The input voltage must be 1.5v higher than the output voltage)
●Adjustable output voltage range 1.25V～37V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)
●The output current is 3A, and it is recommended to use it within 2.0A. The high current needs to strengthen the heat dissipation.
●The output power is 20W, please strengthen the heat dissipation if it exceeds 15W.
●High conversion efficiency, an average of 88% (efficiency is related to input, output voltage, current, and pressure difference)
●With reverse connection protection, reverse connection will not burn
●With overheat protection and short circuit protection
●Size 6.1*3.4*12cm (length*width*height)
●Weight: 22g

Application range:
This module can be used in the step-down field where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supply, 24V car pen-based power supply, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
