In this review I will take a close look at the DROK DC to DC Step Down Buck Converter Module which uses a LM2596 Buck Converter IC
The module also includes a digital voltmeter which can display either the input or output voltage. The output voltage is set by two push buttons. After fully testing the module I found that the best parameters are as follow:
- Input Voltage Range should be from 5 volt to 35 volt (taking the input voltage to 40 volts may damage some modules).
- The output voltage range is stable up to 33 volt.
- The module can handle output currents up to 1.5 Amp O.K. (over that I suggest you add a small heatsink on the LM2596 with thermal glue paste)
- The voltmeter on the module is accurate to +/- 1%.
- Overall the module works very well with stable output voltages.

Nice post. I have a Down Buck Converter. I tried to adjust the potentiometer but the output voltage is same as the input voltage. So, I decide to buy a new one. Please suggest which can be better for me?
The detailed look at ripple and voltage stability was super helpful perfect reminder that even cheap modules often need extra caps for clean output.
