RECOM DC-DC Converter, 5V DC Output, 80% Maximum Efficiency - RFMM Series - RFMM-0505S

Regulate the power supply to your PCB-connected components with this DC-DC converter from RECOM. The unit lets you stabilise input voltages ranging from 4.5 to 5.5V DC to a balanced 5V DC output for small devices like timers and relays. It also creates a barrier between the input and the output, with an isolation voltage of up to 4kV DC, to prevent damage from sudden voltage spikes. The non-conductive plastic housing provides safety during installation without the risk of electric shocks.

Features & Benefits

• Compact dimensions of 19.65 (length) x 7.05 (width) x 10.2mm (height) make it suitable for installation in tight spaces

• Power rating of 1W for energy efficiency

• Broad operating temperature range of -40°C to +85°C for use in extreme conditions

• Through-hole mounting style provides a permanent link for reliable signal transmission

Applications

• Medical equipment

• Telecommunication industry

What's the difference between an AC-DC converter and a DC-DC converter?

An AC-DC converter takes an AC power supply and converts it to an unregulated DC output. A DC-DC converter, on the other hand, regulates DC input from a battery to different voltage levels and, thanks to integrated rectifiers, smooths out ripples from the output signal.
