Use this DC-DC converter from Traco Power to make sure your electronic applications never run out of juice. It steps down an input voltage between 18 and 75V DC to a regulated output voltage of 5V DC that you can use to charge smartphones and laptops. An internal LC-type filter smooths out interference and ensures you get noiseless signal transmission. This component comes with short-circuit, over-voltage and overload protection, so you don't need to worry about faults causing damage. Through-hole mounting gives you a firm attachment to your PCB that won't shake loose in vibrating systems.

• Aluminium housing withstands corrosion to deliver long-lasting performance
• Power rating of 15W suits medium-duty applications
• Isolation voltage of 1kV DC protects connected components from sudden power surges
• 88% efficiency means it makes the most of its energy supply and emits minimal heat
• Maximum operating altitude of 5000m for use in elevated settings

• Telecommunications networks
• Pharmaceutical equipment
• Automotive electronics

The unit is cooled by natural convection, so you don't need to add a heatsink.
