Tipo: LM2596S Convertidor DC-DC
entrada de voltaje: 3 V-35 V.
Voltaje de salida: 1,25 V-35 V.
Corriente de salida: 3 A máx.
Eficiencia de transferencia: 92% máx.
Ondulación de salida: menos de 30 mV.
Frecuencia del interruptor: 65 KHz.
Temperatura de trabajo: -45 a +85 grados Celsius.
Tamaño: 43 x 21 x 14 mm (largo x ancho x alto).
Cantidad: 2 unidades.
Consejos:
1. La entrada y la salida no se pueden invertir, o quemará el módulo.
2. El entrada de voltaje es mucho más de 1,5 V más alto que el voltaje de salida. No se puede utilizar para aumentar el voltaje.
3. Después de la conexión del cable, primero gira una docena de veces, luego ajusta el voltaje mediante rotación en sentido horario.
4. Se recomienda utilizar dentro de corriente de 2.5 A para un trabajo prolongado y necesita añadir disipador de calor si la corriente supera los 2 A (salida superior a 10 W).
Conexión del cable:
1. Soldadura, suelda el cable de alimentación directamente al puerto de entrada (salida).
2. Pin de soldadura, puede insertar el pin con alambre de plomo o insertar en PCB, o soldar en la PCB directamente con pin.

Both failed after using a few cycles, no over-current protection could be the issue, or product quality or design failure, is not recommended.

Llego rapido pero lamentablemente un modulo no prende. Solo por eso doy 3 estrellas

worked perfect to change the voltage for a PC Fan. 24 volts to 12 volts.

I think some of these are being returned due to poor instructions. I purchased these to run 12v fans on a 24v supply and so far the one is working great. (Haven't wired up the second yet). I'll come back and update this review if there's any issues or premature failure."After wire connection, first to turn a dozen times, then adjust the voltage by anticlockwise rotation."Sooooooo turn which direction a dozen times?I'm far from an electronics guru and this took me a bit to figure out based off other reviews so hopefully this helps.Turning clockwise - increases output voltageTurning counter/anti-clockwise - decreases output voltageThere's a LOT of adjustment in the potentiometer that simply will do nothing. Ignore the instructions - if you fire it up and the output voltage is the same as your supply, just keep turning counter clockwise until it starts going down. If you hear a clicking sound coming from the potentiometer it means it's bottomed out (try not to do this I'm guessing it's bad for it). I finally figured this out after cranking it counter clockwise for what felt like 40 turns and it started clicking. Then noticed my output voltage finally changed from 23.3 to basically zero.

I bought this product for use on some older electric trains I work on. Wanted to get a consistent voltage to my train lights (led) and accessory motors, from the track power which is variable. Out of the package and using jumper wires, I had the unit attached to my variable DC power supply. A few turns of he pot and I had consistent 3V output from 3 to 20 volts input. Small enough I can fit it almost anywhere, including some of the smaller HO trains I work on. Great value for the price!

Used this to step down a li-Ion battery pack to 3.05v for a wireless guitar pack that previously chewed through 2xAA batteries. Board is a little taller than I had hoped, but it still fit for my use case. Little light in the board even gave me good insight as to the charge state of the battery.
