Rui Cabral tipped us with his latest video. It’s about a dual output power supply build in a 3D printed enclosure. Main parts used are a 100W AC-DC converter (110V 220V to 24VDC 6A) and LM2596 DC-DC Buck converter constant current voltage adjustable module. The power supply has two voltage outputs, a fixed 5V output […]

by Abid Jamal @ electronicslovers.com: what is Mppt( Maximum power point tracking) ? “we use MPPT algorithm to get the maximum available power from the Photovoltaic module under certain conditions” How MPPT works ? Why 150W solar panel does not equal to 150 w? For example you bought a new solar panel from the market which puts […]

by hugatry @ hackvlog.com: Every now and then someone asks on different forums if there is an way to control cheap LM2596 modules with an Arduino or another microcontroller. I decided to demonstrate one solution that might be basic electronics for some, but still many don’t know about. Those buck converters will change the output voltage […]

by Kerry D. Wong: LM2596 based step-down DC-DC converter modules can be bought on eBay quite cheaply for around a dollar each. But how do they perform? Is it safe to use it to power your design? Let’s find out. According to TI’s website, these LM2596 step-down (buck) regulators are sold for $1.8 each for a […]
