LM2596 DC-DC converter module testing

Kerry D. Wong writes: In the video below, I tested this DC-DC converter board under various operating conditions and measured its efficiencies. To conclude, these switching regulator boards are well suited for low to medium current draw digital circuitry but for higher current applications a heat sink is needed and even so I would not […]

24VAC to 5VDC Conversion

Ray Wang wrote this post about voltage conversion from 24VAC to 5VDC. Voltage conversion from 24VAC to 5VDC is quite useful, because a lot of home automation devices use 24VAC, including sprinkler solenoids, home surveillance systems etc. Having a conversion module makes it easy to use a single power supply, without a separate 5V adapter […]
