Great an valuable step down convertor. Useful for charging a batteries and powering an LEDs from the battery. Works fine for my DIY projects.

Partly as described. Output ripple is greater than the described 50mV. 3 of the components were heated significantly, the inductance of the ic and the diode. At 4A, it was all close to 100 degrees. At 30V input, its idle consumption was 0.44W, increasing to 1-2W during operation. It suits me, it looks better compared to the smaller version. big + that you can set a current limit on it, but then the output turns it off, I haven't tested exactly how it behaves yet.

very useful but the potentiometers are quite difficult to adjust as they need a lot of turn, when replacing them with 10k ones it works perfect

muy útil pero los potenciometros son bastante difíciles de ajustar ya que necesitan mucha vuelta, al reemplazarlos por unos de 10k funciona perfecto
