    I used this module to build a variable power supply. I use an input voltage of 12 volts (from a computer power supply) and need this module to create a variable (settable via the potmeter) output voltage ca 1 - 30 volt. With output voltages over 12 volts everything works fine. In the step down mode (voltages below 12 volt) the output voltage is not stable. For instance if I set the output voltage to 5 volts and apply no or very little load, then the outputvoltage "swings" between 4.8 and 5.3 volt. This only stops if I apply a larger load that draws at least 500mA of current.

    Great product. I used it to build a bench power supply with 2 variable channels and it works fine.

    Order on time and well packaged. I tested it with my countertop source and put a multimeter on the exit and set it for a low tension outlet. It didn't warm up. But I would recommend the utmost care not to reverse the entry tensions because it can give rise to problems. Very small and very compact. I recommend this article. Look at the photos and like.

    Very good, ship with anti-static bag. Product was packed properly. Line regulation is good, tested with 5-30v in input, and 2A load. Suitable for led, or no analog device without filter. Current limitation work fine. I'm bit disappointed on capacitor choice. They are 105degree ones, but only 35V. 50v ones would have allowed a better lifespan.

    This is excellent step-up/step-down converter, that can be used for simple bench power supply. Replace variable resistors with these panel mounting 250 KOhm potentiometers ( ), add solid power supply ( ) voltage/current monitor ( ) and put everything in a nice box ( )

    this converter can help you in solving many power supply problems. it is able to increase or decrese the voltage at its output terminal compared to the input voltage. the output is quite stable with the load change and the multi turns trims help you in adjusting the output voltage level and the max output current as per your needs. One of the thermal pad below the MOSFET was slightly out of position, but I solved this issue very quickly - check the pads before power up the circuit. good value for money. suggested questo convertiore permette di aumentare o diminuire la tensione in uscita rispetto al valore della tensione di ingresso. la tensione di uscita è stabile rispetto alle variazioni della corrente del carico. i trim multigiri permettono una buona regolazione della tensione e della massima corrente di uscita. Un MOSFET aveva il pad termico leggermente fuori posto, ma ho risolto velocemente il problema. suggerisco un controllo dei pad termici prima di dare tensione al circuito ottimo valore per il prezzo. suggerito

    Seems to work well. I will use it to have a portable power pack for all situations (recharge PC, drone Lipos, etc.). Will see how it hold up in time.

    Преобразователь из низкого напряжения от 1.5 вольт может заряжать аккумулятор 12-24 вольта,правда при этом достаточно сильно греется.

    I am using this to boost battery voltage to supply power into a class D amplifier. Now I can use full volume without clipping.

    Works great and it doesnt heat up. Used a 12V SMPS with this and can only reach 1.1V - 29V. I hoped to reach 30V but this has the best value for buck boost converters here. 5 stars!
