Review on 🔌 eBoot Mini MP1584EN DC-DC Buck Converter Power Supply Module - Adjustable 24V to 12V 9V 5V 3V (Pack of 6) by Andargie Marquez

Excellent adjustable buck controls. Don't overheat, maintain a supply voltage with rises and falls that stays within 1-2 hundredths of a volt. gives a fairly clean output voltage (still need an LC filter if you want very clean waveforms) gives 0.6 to 23 volts from my tests. can draw from it a constant 3.5 amps at 16.8v without heating, 2.5 amps at 20 volts heats up, but normal. 3 amps at 20 volts will burn out the coil in about 20 minutes. At 12V I was able to draw a solid 4.2A from it for 2 hours and the temp never went above 97F, 4.5A at 12V it smoked in 7 minutes. If you weld a coil on it, it will NOT pass full voltage (I've had a few buck regulators that fail and let full voltage through for a few seconds. I purposely disabled two of these to make sure the voltage doesn't go through when it hits fails.. and it hasn't happened to any of them and that makes me VERY HAPPY.. the bug acts like a switch, it goes off, it goes off and the circuit breaks immediately.I tested it with an O-scope, and it had 0ms full of voltage loss when it failed.) They're incredibly cheap and great quality. over the preform and remain damn stable. This is without a doubt the best value for money you can buy. A voltage leak of even 1ms can damage voltage-sensitive electronics and ruin your day, and you'll regret not saving those 30 cents a piece.
