RECOM DC-DC Switching Regulator, Built-In Diode Protection Circuit, 220μF Max Capacitive Load - R-78W-0.5 Series - R-78W3.3-0.5


The wrong input becomes the right output thanks to this switching regulator from RECOM. It steps down 6.5 to 32V DC supplies to the stable and noiseless 3.3V DC your low-voltage devices need. To keep you on the safe side, the unit comes with built-in short circuit protection, including an automatic recovery mechanism to ensure you don't lose time to electrical faults. As you don't need to link it to circuit boards to operate it, this is a flexible control solution that's suitable for battery-powered appliances and high-power LED lighting systems.

Features & Benefits


• Broad operating temperature range between -40°C and +85°C for use in demanding settings

• Low ripple and noise rating of 75mV for smooth signal transmission

• Mean time between failures of over nine million hours for long-term performance

• 88% maximum efficiency means it loses minimal power to heat, eliminating the need for a heatsink

Applications


• Process and packaging machinery

• Test and measurement instrumentation

• Automotive industry

How many wires does this regulator have?


For easy reference, this unit comes with three colour-coded wires – red for the input voltage, brown for the output voltage and black for the ground connection.

Recom R-78W-0.5 Series Single Output DC/DC Converter


The Recom R-78W-0.5 series of DC-DC converters are compact, low profile SMD switching regulators. R-78W-0.5 series has a high efficiency of up to 96%, which means that these DC-DC converters do not require heatsinks or fans. The switching regulator can operate reliably between -40°C and 85°C without derating. These DC-DC converters are the ideal space-saving solution for applications where space is limited.
