Want a small adapter with the oomph to reliably energise your equipment? Grab this DC-DC converter from Traco Power. It measures just 13.2 (L) x 9.1 (W) x 10.2mm (D), so it's a cinch to fit on a crowded PCB. The unit is a flexible option that changes inputs between 9 and 36V DC into a steady 9V DC supply. Thanks to its 81% efficiency, little energy goes to waste as heat. When it's operating at full load, you can count on glitch-free performance in temperatures as high as +50°C.

• Tough plastic casing insulates live elements to ensure electrical safety
• 0.2% load regulation indicates input fluctuations have only a minimal effect on the output voltage
• UL 94-V0-rated material means burning stops in 10 seconds to help prevent the spread of flames
• 1600V DC I/O isolation complies with EN 62368-1 standards to prevent damage and downtime

• Industrial and commercial electronics
• Automotive industry
• Testing and measuring devices
• Aerospace systems

Installation is speedy, as you simply punch the pins through the holes on the PCB and solder them.
