LM2596 DC-DC Module with Voltage Display

Overview

The LM2596 DC-DC module with voltage display is a step-down voltage regulator which has a wide input range (between 4 V and 40 V) and the output voltage is adjustable using the potentiometer between 1.25 V and 37 V. This module has good quality and its voltage display does not require additional power.

This DC-DC power module can output a current up to 3 A and it's suitable for a wide range of applications which need a high-efficiency power converter. To operate at full capacity, it is recommended to use an additional cooling system. If you have a constant source of 30 V to 35 V, this module is ideal to build its own adjustable power.

Specifications

• Input Voltage: 4 V to 40 V
• Output Voltage: adjustable between 1.25 V and 37 V
• Maximum Output Current: 3 A (with additional heat sink); 2 A (without heatsink)
• Output Power: 15 W without radiator (20 W with radiator)
• Maximum efficiency: 88%
• Ripple: 30 mV
• Operating frequency: 65 kHz
• Size: 61 mm x 34 mm x 120 mm

Features

• With voltmeter display and the voltmeter can be self-calibrated. Using a more advanced voltage microprocessor, the voltmeter error is ±0.05V , and the range is 0~40V . ( To ensure the accuracy of voltmeter, please ensure that the input voltage is 4.5V or more )
• 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 . Large currents need to strengthen 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

Applications

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 supplies, 24V car pen-meter power supplies, industrial equipment step-down, 12V to 3.3V , 12V to 5V , 24V to 5V , 24V to 12V , 36V to 24V, etc.
