## Description

Product description

Review: Dont even skimp on voltage regulators or you will pay for it.. these are great!!! - Excellent adjustable buck style voltage regulators.. don't get hot, provide a soild voltage feed with raises and falls that stay within 1 to 2 hundredths a volt.. give a fairly clean output voltage (still need a LC filter if you want very clean wave forms) provides 0.6 to 23 volts from my testing.. able to pull a constant 3.5 amps off it at 16.8v without it getting hot 2.5amps at 20volts gets warm but ok... 3amps at 20v will cook the coil in about 20 minutes.. at 12v I was able to pull a solid 4.2a off it for 2 hours and the temp never got above 97F, 4.5a at 12v smoked it in 7 minutes... If you cook the coil on it it does NOT allow full voltage to pass through (I have had some buck regs fail and allow full voltage to pass through for a few seconds.. I killed two of these intentionally to make sure that when it failed no voltage pass through and on neither one did that happen and that makes me VERY HAPPY. A failure acts like a breaker, it fails it fails and circuit is instantly broken.. I tested this with a O-scope and it had 0ms of full voltage seep when it failed..) These are incredibly cheap and excellent quality.. over preform and stay dang steady.. These are without a doubt the best cost to preformance ratio bucks you can buy... Bucks are not a place to skimp and buy as cheap as possible BECAUSE a failure on a buck that is supplying constant regulated voltage to high dollar electronics and fail and allow unregulated voltage to seep by for even a 1ms can damage sensitive to voltage electronics and ruin your day and make you wish you wouldn't have saved that 30 cents per piece.
Review: Great way to reduce fan speed - I used this to reduce the speed of a 24V fan, making it nearly silent. I snipped the fan wires and soldered them onto this board, then taped it down. Turned on the fan and adjusted the screw until it was the right balance of airflow and noise. Overall, works really well and price is great.

### ⭐⭐⭐⭐ Good Compact Buck Converters, But Test Them First
*by S***X on May 6, 2026*

I bought the 3-pack of these MP1584EN buck converter modules, and 2 out of the 3 worked. The one that didn’t work had visible damage: the MP1584EN regulator IC was cracked, and after testing it, I confirmed that the chip was shorting out. I’m not sure if that happened during shipping or before it was packaged, but the other two modules worked fine. For the working ones, they have been good little buck converters. They are very small, which is nice for compact electronics projects where space is limited. The voltage adjustment works well and is very precise, but the potentiometer is sensitive, so it takes small turns to dial in the exact voltage you want. Once adjusted, it held the voltage fine for my use. I also did a quick current test on one module by briefly shorting the output through a multimeter in amps mode, and it showed around 500 mA. That may just be the module’s short-circuit protection kicking in, so I don’t think that means it can only output 500 mA. It may be able to supply more with a proper load that actually draws current instead of a direct short. For my low-power project, though, it was more than enough, and the working modules never really got warm. Overall, I like them. They are small, easy to use, and work well for low-power electronics projects. I’d just recommend testing each one before installing it permanently, especially if you are using them for something important.
