DC-DC Step Down Voltage Converter Adjustable 3A LM2596HVS (4.5~60Vdc to 3~35Vdc) SKU#DC100HVS

The LM2596HVS step down converter is an adjustable DC-DC module that lowers a higher DC voltage to the level your circuit needs. It accepts an input from 4.5V to 60V, gives an output you can set anywhere from 3V to 35V with a potentiometer, and delivers up to 3A, which makes it a practical way to power boards and devices from 12V, 24V or higher DC supplies.

• Working temperature: industrial grade (-40 C to +85 C)
• Load adjustment rate: + 1%
• Voltage regulation rate: 0.5% (to achieve the output voltage when the output voltage is higher, but as long as there is a 1mA load, the output voltage will be normal, does not affect the function, please rest assured that use.
• Short circuit protection: current limit, overheat protection, self-recovery.

LM2596HVS Step Down Converter: A Wide Input Range of 4.5V to 60V

This LM2596HV buck module is based on the LM2596HV regulator, the high-voltage version of the LM2596 family. The manufacturer's datasheet lists an input range of up to 60V, a guaranteed load current of 3A and a fixed 150 kHz internal switching frequency, which keeps the circuit compact and efficient. The module also includes current limiting and overheat protection, and it recovers by itself after a short circuit, as listed on this page.

Adjustable DC-DC Buck Converter 3A: Setting the Output Voltage

As an adjustable DC-DC buck converter 3A module, the output voltage is set with the onboard potentiometer anywhere between 3V and 35V. Set it with no load connected: power the module, measure the output with a multimeter, and turn the potentiometer until you reach the voltage you need, then connect your device. Remember the dropout voltage of 1.5V: the input must stay at least 1.5V above the output you want, so a 24V output needs an input of at least 25.5V. Keep the load within the module's rating (2A rated, 3A maximum) and give it airflow if it runs warm.

60V Input Buck Converter: Where It Fits

A 60V input buck converter is useful when your power source is higher than a standard 12V adapter, for example a 24V supply or a multi-cell battery pack that must be reduced to 5V, 9V or 12V for controllers, sensors and small motors. Because it is a step-down (buck) design, the output is always lower than the input. If your source is below 38V and you do not need the wider range, compare it with the LM2596S adjustable converter (4~38Vdc input). If your load needs more current, see the XL4016 8A step down converter.

Frequently Asked Questions

What is the input voltage range of LM2596HVS?

The module accepts 4.5V to 60V DC.

What is the output voltage range?

The output is adjustable from 3V to 35V DC with the onboard potentiometer.

How to adjust the output voltage of an LM2596 module?

Power the module with no load connected, measure the output with a multimeter, and turn the potentiometer until you reach the voltage you need. Then connect your device.

What is the difference between LM2596S and LM2596HVS?

The LM2596HVS is the high-voltage version, and this module accepts inputs up to 60V. The standard LM2596S module in our store accepts inputs of 4V to 38V.

What is the maximum output current?

The module is rated at 2A, with 3A as the maximum.

Can a buck converter step up voltage?

No. A buck converter only steps voltage down, so the output is always lower than the input, with at least 1.5V of dropout.

What protection does the module have?

It has current limiting and overheat protection, and it recovers by itself after a short circuit.
