Is finding an efficient switching regulator your top priority? Look to this DC-DC converter from RECOM. It accepts inputs anywhere between 4.5 and 18V DC and steps them down to an adjustable 3.3V DC with an accuracy of ±1%. This makes it practical for running your sensitive DC-powered components. A 91 to 93% efficiency rating means minimal energy is wasted as heat and you won't need a heatsink to keep things cool. You can trust this is a reliable choice thanks to its comprehensive electrical safety mechanisms, including overload and short-circuit protections with automatic recovery. There's even remote ON/OFF control so you can manage your device from a distance.

• Typical load regulation of 1% means you get tightly controlled output values
• Autosense function compensates for losses caused by long circuit loops
• Flame-retardant package materials help ensure safety in case of fire
• Mean time between failures of 749,000 hours, so it's a long-lasting choice

• Renewable energy circuits
• Smart lighting
• Medical devices

You can use this unit across an operating temperature range of -40°C to +85°C, so it's a safe bet for demanding industrial settings.
