.In this video you will see the test result of a buck converter module based on LM2596 regulators.
The module is tested under different voltage and current and result is presented so the user can judge.

  • Thanks for video mate. It is very useful. I watched bunch of your other videos all of them good and useful. Thanks for your hard work 🙌

  • PREGUNTA IMPORTANTE: si dices que la fuente suministra hasta 3A de corriente porque la bobina soldaje SMD segun su codigo 101 me dicen las especificaciones que solo da hasta 1A max de corriente, este componente no estaria actuando como la fuente de electrones de la fuente misma, aqui el link de las especificaciones: https://www.digikey.com/product-detail/es/DR1030-101-R/513-1323-1-ND/1130406

    Thank you. I have recently purchased three converters from different places: Singapore, Georgia, Nevada but none worked. Your testing was appreciated.

  • IF THE "OUT "VOLTAGE DOES NOT WORKS (DO NOT CHANGE) THEN DO THIS:
    TURN THE DIAL COUNTER-CLOCKWISE AT LAST 10 TIMES AND IT WILL START WORKING AGAIN !

  • Thanks for sharing this info! I have 8v in and i want 12v out but it wont let me increase the voltage.. Can this module increase voltage output or mine is broken?

  • If I have a 24V/10A power supply in to the LM2596, and I'm stepping it down to 12V/420mA for a DC pump, do you think it will still run as hot? I am worried that the LM2596 will always draw 10A as opposed to my pump drawing just what it needs. Thanks Robojax

  • My device is showing output like 5v but when I measure it.. it gives same voltage as an input 12v.. can i fix it somehow? Also the potenciometer has no effect.
