6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step Down Module

These are good to have on hand for hobby electronics or project builds. Versatile.

The 10 units arrived inside of a box, sealed individually inside anti-electrostatic packaging.I hooked up each individual buck regulator and it's a 10/10 for me as far as getting working units goes. The potentiometer needs a solid 5 or 6 turns counter-clockwise for the voltage to come down, but I got all of them down to 5v from a 12v source. Did some quick load-testing by connecting power resistors to see if the voltage would drop, it did not. Unfortunately I don't have a scope handy so I can't comment on the output noise. I think as a simple power supply for home crafts and DIY projects these will suffice just fine.Build quality is perfectly reasonable, if anything I wish the through-holes were a bit bigger as well as the soldering pads, but it's still workable if one doesn't try to connect a 14G wire.

Los reguladores funcionan excelente los he cargado hasta 3.2 amperes a una salida de 7.5volts hasta el momento no se han dañado, porsupuesto con su debido disipador, lo único malo sería que el LED indicador es color rojo pero aún así se los retiré, vienen las 6 piensas en empaques individuales dentro de una caja, muy buen producto. Gracias Amazon por tus servicios

I originally bought these for a home solar project as I needed to convert 6V to 3.3V. I then used another from 12V to 5V conversion. Then I used another to fix a charging problem in another device. There working well so far and I am chuffed that I am using them up and they are not languishing in a storage box.Is this a "Right place Right time" purchase or a product that fits well, at a good price, nice delivery and my gadgets are working. Yay!

I built a Max97220 headphone amplifier/line driver/preamplifier and to prevent it ever being destroyed by overpowering the 5 volts DC limit, I used this power supply regulator. I blew up the first one with reverse polarity so I added two 1N4004 diodes to the front to prevent reverse polarity destruction. The diodes drop a few millivolts but better safe than sorry. Works like a charm. The resistor in the photo was just a dummy load for test and setup but I ended up leaving a 10k ohm resistor in parallel with the MAX97220 supply VCC to maintain an idle current of 0.5mA on the 2596 board. It also has an LED in series with a 1k ohm resistor drawing another 3mA. The 1N4004s turned the LM2596/Max97220 combination into a radio receiver so I connected the audio ground on the negative terminal of the LM2596 PCB and it ran 100% perfect and silent.Great little board!
